Interpreting dreams

According to popular dream interpretation manuals, if you dream about a cat, that means you are thinking about female sexuality. Parrots in dreams, on the other hand, symbolize gossip, or that "a message is being conveyed to you," or that "someone is being repetitive or even mocking you." I mention all this because I had lots of cat dreams as a child, and plenty of parrot dreams as a teenager. Of course, the fact that I've been around cats since I was four, and acquired a cockatiel when I was older, has nothing to do with it.

Never do these manuals stop to consider that dreams might be based on memories of daytime experiences. They always start from the assumption that all concrete objects are metaphors for suppressed emotions and anxieties, often of a sexual nature. Where they get these explanations I have no idea. It all sounds to me like a rather clichéd attempt to apply literary analysis (with Freudian overtones) to dream narratives.

Still, it's curious that some dreams seem so widespread. For example, lots of people report dreaming about accidentally going outside without clothing. Other common dreams include flying, or falling, or having one's teeth fall out, or facing an exam after having forgotten to come to class the entire semester. If dreams are particular to individuals, why are some of the most absurd ones nearly universal?

My personal theory is that dreams depict events that we expect might happen based on our life experiences. Many dreams consist of little more than distorted memories mixed together. Whenever I dream about an experience I've never had, I get the sense that my dreaming mind believes it could happen. There are things I desire which I never dream about, because I don't expect them to happen. Thus, I'm inclined to reject Freud's theory of dreams as wish fulfillment, even though I know he would argue that my subconscious mind suppresses my true desires.

An important mechanism in dreams is exaggeration. I once dreamt I was visiting a friend who in real life has one cat, but in the dream had five. I've also had dreams in which my own pets spoke English--not just my parrot, but my cats as well. I believe this reflects the way I anthropomorphize animals, thinking of them in such human terms that I practically expect them to talk. Only common sense (which I lack during sleep) makes me know better.

What about nightmares? How do they fit my theory? The answer is that when we're anxious about something, some part of us expects it to happen. That explains the feeling of inevitability in nightmares, nicely captured in The Wizard of Oz when the lion appears as soon as Dorothy begins worrying about "lions and tigers and bears." Those dreams in which we triumph over scary things, as Dorothy ultimately does, reflect our confidence.

As for the dreams where we walk outside without clothes, I suspect that they stem from our anxiety over relying on habit to get through daily routines. Most of the time when we dress ourselves, we aren't thinking about the activity at all. Just as we're occasionally forgetful with other habitual activities, it is semi-plausible (and I believe it has happened) that someone might forget to put on a vital piece of clothing. In the embellished world of a dream, that fear translates into reality.

As it stands, scientists now believe that REM sleep (the period in which most of our dreams occur) serves a memory-related function. It almost appears as if we're not meant to remember any of our dreams. We experience a kind of amnesia upon awakening, in which we quickly forget what we were dreaming about, unless we make a special effort to remember.

There are people who claim never to dream, but scientists assert that everybody dreams. Some people just don't remember. How do scientists know? In the sleep experiments of the 1950s which revolutionized the field, all the subjects, even those who initially denied ever dreaming, ended up reporting dreams at the moment the researchers awoke them from REM sleep.

The study of dreams presents many scientific difficulties. If a person says, "I dreamt I was a dog last night," we have to take his word for it. It's like basing our testimony on an amnesia patient who was the only witness to an event. We know that dreams don't occur in physical reality, but how can we verify that they occur at all? How do we know, as scientists currently believe, that they are hallucinatory experiences that occur in real time during REM sleep?

The 1950s researchers would awake sleepers who had just gone through a REM cycle (detected with an electroencephalogram) and ask them to approximate how long their dream had lasted. The scientists found a positive correlation between the length of the dream reported and the length of the REM cycle observed. They also studied the effects of external stimuli on dreams. In one case, a scientist dripped water down a subject's back thirty seconds before waking him. The subject reported having dreamt about singing at an opera, when molten wax suddenly began dripping from the ceiling.

The best book on dreaming I've read is J. Allan Hobson's 1988 The Dreaming Brain, which includes a remarkable amount of scientific information (much of which went over my head) as well as a theory that ties these observations together with stunning simplicity. The book is one of a kind: most books on dreaming focus either on the subjective aspects (and usually wind up sounding hokey and unscientific) or purely on the scientific observations (which are too limited to tell us much about the subjective state of dreaming). Hobson finds a middle ground where he is able to quantify the characteristics of dreaming and correlate them with the findings of neurobiology and sleep research.

I learned from this book that the portions of our brain governing movement and sight are activated during REM sleep. Hobson proposes that the ultimate source of dream sensation--which seems to be predominantly visual and motor--is physical rather than psychological. It is no wonder that dream sensations feel largely involuntary. As Hobson puts it, "we seldom have the experience of willing the movements that occur in dreams, but instead experience a sense of compelled or involuntary motor activity over which we have little or sometimes no control. This contrast is particularly and strikingly sharp in those dreams in which motor activity becomes a central part of the plot: for example, when one attempts to escape from a pursuer" (p. 171). This also helps explain the sensation of rapid movement we frequently experience during dreams. If we're anxious, we perceive that we're falling; otherwise, we may perceive that we're flying.

Since the sensations are physiological in origin, Freud was wrong: dreams are not messages from our subconscious (or from anywhere else, for that matter). But here's the catch: our thought reflections, which help organize the sensations into a narrative, infuse the dream with meaning. This meaning, according to Hobson, is usually transparent rather than oblique:

The activated brain-mind does its best to attribute meaning to the internally generated signals. It is this synthetic effort that gives our dreams their impressive thematic coherence: dream plots remain remarkably intact despite their orientational disorganization. And it may be that their symbolic, prophetic character arises from the integrative strain of this synthetic effort. The brain-mind may need to call upon its deepest myths to find a narrative frame that can contain the data. Hence, one can continue to interpret dreams metaphorically, and even in terms of the dynamically repressed unconscious, if one so chooses. But such a practice is no longer either necessary or sufficient as an explanation of either the origin or the nature of dreaming. (p. 214)

A recent dream of mine exemplifies this discrepancy. I dreamt that people's faces kept turning into non-digital clocks. Interpreting this dream reveals the different possible ways of answering the question "Why did I have this dream?" It could have been that I had been walking around in the early morning and glanced at a non-digital clock on the wall; the image stayed in my mind so that when I conjured up images of people's faces, my memory of the clock came back to me. Dreams are good at finding analogies. But the dream may also have reflected my feelings over my grandfather's recent death, an event that has made me think lately about how life is finite. In the dream, I expressed this feeling by seeing people as ticking clocks.

Symbolic dreams of this kind are probably a function of the individual dreamer, rather than an expression of universal mythic archetypes. People who have symbolic dreams are probably symbolic thinkers; concrete individuals will tend to dream in concrete terms. Still, human dreams might have a lot to do with why we exhibit more creativity than other species. The biochemist Otto Loewi claimed that the experiment which led him to the postulations of chemical neutrotransmission--and earned him a Nobel Prize--occurred to him in a dream, and Robert Louis Stevenson based his story "Dr. Jekyll and Mr. Hyde" on a dream.

The important point is that our reactions to dream sensations prove just as important as the sensations themselves in establishing the dream "plot." This is not to suggest that dreams have no meaning. They certainly do, but according to Hobson, the meaning is usually more transparent than both Freudians and mystics would believe. Don't waste your money on a pseudoscientific dream manual; most likely, you are your own best dream manual.

A paranormal romance

I recently discussed my love of the Richard Matheson novel What Dreams May Come. Now I'm going to talk about another Matheson novel, Somewhere in Time (originally titled Bid Time Return but later changed to fit the movie). I cannot exactly recommend this novel. In fact, I thought the 1980 film version improved on it considerably. Matheson, however, considers this book and What Dreams May Come to be his two greatest novels. He may even have conceived them as one book. The similarities between the two are striking. The protagonists in both books are blond 6'2" screenwriters who live in Hidden Hills, California and love classical music. They each have a brother named Robert who acquires the protagonist's memoirs but cannot bring himself to accept the otherworldly events described in them. Both books are paranormal love stories, but they emphasize different phenomena.

In Somewhere in Time, a 30-something man named Richard Collier has been diagnosed with an inoperable brain tumor and has decided, upon a coin flip, to spend his last days hanging around the Hotel del Coronado, a famous California hotel. There he grows obsessed with the photograph of a nineteenth-century stage actress, Elise McKenna, who once performed there. Through research, he learns that she never married, that she had an overprotective manager, and that she may have had a brief affair with a mysterious man while staying at the hotel. The more Richard learns, the more convinced he becomes that it is his destiny to travel back in time and become that mysterious man.

This is an interesting setup. But the execution is shaky. I barely could get through the first fifty pages, which consist of Richard's rambling journal entries as nothing happens. I realize that Matheson was attempting realism, but I don't consider that a good excuse. A novel must involve the reader or it isn't worth our time. The book's deepest flaw, however, is the love story itself. I simply did not like the character of Elise. The development of her relationship with Richard feels artificial and forced. It's definitely a case of the journey being more interesting than the destination.

The novel's most striking feature is its depiction of time travel. It's probably the only novel I've ever encountered that proposes a step-by-step method that does not require any futuristic accessories or special abilities. The method is presented in such detail that it almost tempts readers to try it themselves. I bet that some have, though I have my doubts that any have succeeded.

Richard bases his method on the theories of a real book, J.B. Priestley's Man and Time. The basic idea is that he uses self-hypnosis to convince his mind that he's in the past. He listens over and over to a tape recording of his own voice declaring that the year is 1896 and listing many details of how his surroundings would look in that year. After discovering that his voice is distracting him, he writes the hypnotic suggestions out on paper, over and over and over. The historical roots of the hotel help reinforce his purpose, as does an 1890s suit he buys for himself.

Of course, skeptical readers may suspect that the time-traveling experience occurs only in Richard's mind. Matheson leaves open that possibility. So if you think the love story is unconvincing and seems more like a lonely man's pathetic fantasy, that may be just what Matheson intended.

The movie does a better job of handling these themes. The plot is clearer and more focused. There's no mention of Richard having a brain tumor, and there seems to be external evidence that his journey really took place, such as in an early scene where an old woman goes up to him in a crowd and hands him a pocket watch and says, "Come back to me." He later takes the watch with him into the past, where he gives it to the woman when she's young. This generates one of the most famous time-travel paradoxes in the movies, the watch that seems to have no point of origin, just eternally existing in an endless loop. The book contains other paradoxes of this kind, but more subtly.

While the movie did poorly in theaters and receieved mostly negative reviews, it went on to become a cult classic, with an actual fan club. Being less than enamored by the love story, I was only able to admire the film's craft. It felt to me like an episode of The Twilight Zone, a show to which Matheson contributed heavily. But neither the book nor the film enthralled me the way the novel What Dreams May Come did, perhaps because this time I wasn't truly permitted entry into a new world.

The science of fruits, nuts, and flakes

Some years ago, not long after reading parts of Carl Sagan's The Demon-Haunted World, a book about the remarkable persistence of superstitions among educated people, I discovered that a highly intelligent woman I know, who has a science degree and has always seemed rationalist in her outlook, believes in astrology. She described the traits of my sign, Aquarius, and they did seem to fit me fairly well. I don't remember her description now, so instead I'll post what Wikipedia says about the sign:

Individuals born under this sign are thought to have a modest, creative, challenging, inquisitive, entertaining, progressive, stimulating, nocturnal, and independent character, but one which is also prone to rebelliousness, coldness, erraticism, indecisiveness, and impracticality.

I have to admit that that does kind of sound like me. I like to think of myself as creative, challenging, and independent. I know I am impractical and indecisive, and unquestionably I am nocturnal. On the other hand, the article also claims that male Aquarians "are often said to tend to be effeminate in appearance." Hey, I may not be the most macho of sorts, but I sure as hell ain't effeminate looking.

But there lies the problem. One of the most obvious features of pseudoscience is allowing subjectivity to influence the testing of predictions. Having people examine their own personalities is notoriously unreliable, since people tend not to have accurate perceptions of themselves. What exactly would constitute a "bad" astrological reading? If you didn't feel the description sounded like you? If your friends didn't think so? And how close does the description have to match your personality in order to prove that its alleged accuracy isn't merely coincidental? (For example, I suspect that there are many creative and independent types not born under Aquarius.) Astrologers never set up any quantifiable boundaries by which their "predictions" can succeed or fail. It's all left up to the whim of the person reading the horoscope.

Still, I can imagine ways in which the claims of astrologers might be tested. Gather a group of people together, and give only some of them their true astrological readings. Give the others a deliberately false reading. For example, the Gemini gets the Scorpio's reading. None of the people know whether they are receiving a correct reading or not. Perhaps none of them know there even are any incorrect readings. Even the person doing the testing doesn't know which ones are correct and which ones aren't. The subjects are then asked to rate their readings, on a scale of one to ten, by how closely they feel it describes them.

Now comes the fun part: compare the reactions of the people who got false readings and the people who got true readings. If the claims of astrology are valid, then the people who got true readings should be substantially more likely to think the readings accurately describe them. If, on the other hand, there isn't much difference between the reactions of the two groups, then the claims of astrology would seem to be bogus.

Has anyone ever tried such an experiment? Do believers in astrology even care? Hey, I know that even this test probably wouldn't pass muster with the scientific community. It still has the problem that people are examining their own personalities, rather than being objectively evaluated by a disinterested outsider.

Of course, many scientists will dismiss astrology out of hand simply because of its premise that celestial bodies many light years away can have a perceptible effect on human behavior. But I'm willing to entertain this premise for the sake of argument, because astrology in principle does make real predictions about observable facts. If those predictions were scientifically confirmed, we'd have to concede that there's something to the system, no matter how absurd its philosophical underpinnings may sound. Skeptics can take comfort from the fact that we're a long way from ever having to confront that possibility.

The most overlooked novel

We generally expect books to be better than their film adaptations. The most extreme example from my experience may be What Dreams May Come. I strongly disliked the 1998 film, and I probably would have quickly forgotten about it, except that I noticed it was based on a 1978 novel by Richard Matheson, whose fiction I had enjoyed previously. So I picked up a copy from the library. It has since become one of my favorite books.

I am not alone in this reaction, but I am in a minority. Most people haven't read the book, and most people won't even try. There are just too many preconceptions standing in their way. And, unfortunately, the movie has helped further those preconceptions. People assume it isn't the type of book they'd like to read. They think it is too "New Agey" for their tastes, or too sentimental. On the first point, they are probably correct; on the second, they couldn't be more wrong.

Why do I like the book so much? Put simply, it is the most vivid, complex, and surprisingly convincing depiction of afterlife I have ever encountered in a work of fiction. Nothing else I have seen on the subject, in literature or in film, comes close--certainly not the movie version of the book. Before I read the novel, I had no idea that a story about Heaven and Hell could have such a profound effect on me. I have always believed in afterlife as a matter of faith, but I would never before have thought it could be convincingly described in human terms.

The story involves a middle-aged man named Chris who dies and goes to Heaven, and who ultimately descends into Hell to rescue his wife. It's basically a modern-day variation on The Divine Comedy, as a man gets a tour of the afterlife. In the metaphysics of the film and the book, dying involves shedding your physical body and entering a mental environment shaped by thoughts. Your fate in such an environment is largely self-imposed. If you're a decent, pleasant person, your afterlife experience will be pleasant; if you're someone with moral problems, you'll naturally have a more difficult experience. As the novel puts it, "People are not punished for their deeds but by them" (p. 265).

That much of the movie intrigued me, the first time I saw it. The problem was the schmaltz. I mean real schmaltz, piled on in large mounds, in place of strong narrative. The beginning gives us scene after scene of two lovers (Robin Williams and Anabella Sciorra) doing little more than stare at each other and giggle, with solemn music in the background. The film is so inept at fleshing out their lives that it shows their wedding, the tragic death of their children, and fifteen years passing before it reveals out of the blue that Chris is a doctor! The performances by Williams and Cuba Gooding, Jr. are surprisingly atrocious, maybe because they could scarcely believe their own lines.

For those who have only seen the movie, it's hard for me to convey just how very different the novel is. Of course there are major differences in the plot. One such difference is the ending. (Even Roger Ebert, who heaped high praise on the film, was disappointed by the ending.) Another is the beginning, where the film has Chris's children also die and go to Heaven. In doing this, the movie (1) makes the early scenes so depressing they become surreal (2) needlessly clutters the story with extra characters (3) introduces a silly and confusing subplot about Chris's attempts to find his children, who are in disguise.

In the book, Chris's children are adults, not youngsters, and they're minor characters. The details of Chris's life on Earth differ so greatly between the book and the film that it's like reading about a completely different person. Even though I saw the movie first, the image of Robin Williams completely vanished from my mind as I read, because he was so unlike the character described in the book.

The entire feel of the book is different, telling a touching love story that uses real characterization, not cheap manipulation, to move the audience. And Matheson's vision of the afterlife truly comes alive on the page. The Hell scenes are actually terrifying, reminding us, as the movie does not, why Matheson is primarily famous as a horror writer.

I won't overlook the movie's gorgeous visual effects, which earned the film a well-deserved Academy Award. They just aren't put to good purpose. The movie's vision of the afterlife as like being inside giant paintings fails to evoke a sense of reality. The book, in contrast, bases its afterlife imagery (vividly brought to life by Matheson's skillful prose) much more on Earth-like scenery. This approach ironically leads to far more exotic ideas, such as architects who build things using their minds, and a library containing history books more objective than those on Earth. Matheson puts the reader right inside this setting, as the following passage illustrates:

I noticed, then, there were no shadows on the ground. I sat beneath a tree yet not in shade. I didn't understand that, and looked for the sun.

There wasn't any.... There was light without a sun. I looked around in confusion. As my eyes grew more accustomed to the light, I saw further into the countryside. I had never seen such scenery: a stunning vista of green-clad meadows, flowers, and trees. Ann would love this, I thought.

I remembered then. Ann was still alive. And I? I stood and pressed both palms against the solid tree trunk. Stamped on solid ground with my shoe. I was dead; there could be no question about it any longer. Yet here I was, possessed of a body that felt the same and looked the same, was even dressed the same. Standing on this very real ground in this most tangible of landscapes....

I turned my hands over and noticed that their skin and nails were pink. There was blood inside me. I had to shake myself to make certain I wasn't dreaming. I held my right hand over my nose and mouth and felt breath pulsing warmly from my lungs.... (p. 55-6)

And here is a passage from one of the book's Hell scenes: "Now I saw that, interspersed throughout the area we crossed, were pools of dark and filthy-looking liquid; I hesitate to call it water. A loathsome stench beyond that which I had ever been exposed to rose from these pools. And I was horrified to see movement in them as though unfortunates had slipped beneath the surface and were unable to rise" (p. 183).

Matheson, as I mentioned, is a famous horror writer. One of his unique qualities is his almost scientific approach to the supernatural. As Roger Ebert explains in his review of the Matheson-penned Legend of Hell House:

Matheson labored for years in the elusive territory between straight science fiction and the supernatural horror genre, developing a kind of novel in which vampires, ghouls, and the occult are treated as if they came under ordinary scientific classifications.

There was, for example, the Matheson classic I Am Legend.... In that one, a single normal man held hundreds of vampires...at bay by figuring out the scientific reasons for old medieval antivampire measures like mirrors, crucifixes, and garlic. The Matheson novels of the 1950s and early 1960s anticipated pseudorealistic fantasy novels like Rosemary's Baby and The Exorcist.

In What Dreams May Come, Matheson makes Heaven and Hell seem like a scientific, natural process, and one of the joys of the book is discerning all the intricate "rules" of how everything works. (That's another area where the movie falls short.) What needs to be kept in mind, however, is that Matheson doesn't do this just for entertainment purposes. In the novel's introduction, he tells his readers that the characters are the only fictional component of the novel, and that almost everything else is based on research. The book even includes a lengthy bibliography. Thus, the afterlife that Matheson describes isn't some fantasy world he concocted from his own head, but something he believes to be an accurate description of reality.

Some people may wonder, at this point, about Matheson's religious background. He was raised a Christian Scientist, but gradually developed what he calls his own religion, taking elements from many sources. One of the book's main influences, I believe, is eighteenth-century Christian mystic Emanuel Swedenborg.

The book avoids seeming "religious" in any way other than its setting. There are no deities, no mention of Christ or anything specific to the theology of a particular religion. The characters occasionally talk about God, but it is left up to the reader to decide whether the Creator in charge of this system is at all like the Judeo-Christian God or like something more pantheistic. The book even implies that no single religion has the whole truth:

"For instance, you'll find, in the hereafter, the particular heaven of each theology."

"Which is right then?" I asked, completely baffled now.

"All of them," he said, "and none. Buddhist, Hindu, Moslem, Christian, Jew--each has an after-life experience which reflects his own beliefs. The Viking had his Valhalla, the American Indian his Happy Hunting Ground, the zealot his City of Gold. All are real. Each is a portion of the overall reality.

"You'll even find, here, those who claim that survival is nonsense," he said. "They bang their nonmaterial tables with their nonmaterial fists and sneer at any suggestion of a life beyond matter. It's the ultimate irony of delusion." (pp. 90-1)

From what I've seen, people react negatively to this book based on how far it departs from their personal beliefs. Christians complain about the absence of Jesus, while those who don't believe in any afterlife consider the story too nonsensical to accept. Most readers, it seems, are put off by the New Age terminology and concepts scattered throughout the book.

These reactions are puzzling, if you stop to think about it. Books about elves, fairies, dragons, and wizards remain popular even though nobody believes in any of those things. Why should people be bothered by a fiction book portraying a Heaven and Hell that conflicts with what they believe? The book is perfectly enjoyable whether or not you accept Matheson's metaphysics.

Of course, I personally do think Matheson provides insight into the subject--though I admit I'm a little wary of his acceptance of paranormal phenomena. But it amazes me how so many people refuse to even touch the book, thinking that any story with such a plot must automatically be hokey. In most cases, they'd be right. What Dreams May Come is a big exception. It suggests the endless possibilities in a subject that normally is dead weight for fiction. And it really makes you think.
