The Value of Daydreaming

I am a chiropractor who often must sit with patients and look them directly in the eyes contact while explaining my findings after a lengthy physical. During these times I’m often fascinated to observe who is actually listening and who has gone off to “the Bahamas,” as I often think it. Though I can see the effects of losing a person’s attention, I can never quite pinpoint when that shift takes place. Is there a precise “moment” when our minds shift from attention to wandering into the realms of possibility and potential? A new study on “mind-wandering” indicates that there is.

The study was recently published in PNAS by a group of scientists, led by Kalina Christoff of UBC and Jonathan Schooler of UCSB. They used  fMRI to capture the moment of daydreaming. The subjects were given an extremely tedious task and, when their mind started to wander, the changes in their brain activity were recorded in the scanner.

The results suggest that mind-wandering may evoke a unique mental state that may allow otherwise opposing networks in the brain to work in cooperation. In recent years scientists have demonstrated that daydreaming is such a fundamental feature of the human mind that it’s frequently referred to as the “default” mode of thought. Daydreaming, scientists argue, is a crucial tool for creativity. Instead of focusing on  immediate surroundings, the daydreaming mind is free to engage in abstract thought and imaginative ramblings. (Not good news when a patient needs to hear a diagnosis, a child needs to pay attention in class, or someone driving a car needs to be fully focused.)  And, as a result, we’re able to imagine things that don’t actually exist.

“If your mind didn’t wander, then you’d be largely shackled to whatever you are doing right now,” says Jonathan Schooler, a psychologist at the University of California, Santa Barbara. “But instead you can engage in mental time travel and other kinds of simulation. During a daydream, your thoughts are really unbounded.”

I’m all for “unbounded” thought, but unfortunately the mind of many of us appears to “free” itself, unexpectedly, and when it needs the boundaries of focus. Not all daydreaming is productive or creative, but it may be necessary. Maybe we all need “daydreaming breaks” throughout the day to allow our mind the freedom (and safety) to roam.

What Are Your Dreams Made Of?

What’s in a dream? To Freud, dreaming provided a playground for the unconscious mind. To Jung it was a stage where the psyche’s archetypes acted out primal themes. To newer psychologists, dreams help the brain to consolidate emotional memories or to work though current problems, like divorce and work frustrations. To chiropractors, dreams simply mean that their patients are sleeping at night!

What if the primary purpose of dreaming isn’t psychological at all? Weird concept? Well, in a paper published in the October issue of the journal Nature Reviews Neuroscience, Dr. J. Allan Hobson, a psychiatrist and longtime sleep researcher at Harvard, argues that the main function of rapid-eye-movement sleep, or REM, when most dreaming occurs, is physiological. Whoa! Physiological? Now, that’s right up a chiropractor’s philosophical alley!

Dr. Hobson believes that the brain is actually warming its circuits in anticipation of the sights and sounds and emotions of waking. “It helps explain a lot of things, like why people forget so many dreams,” Dr. Hobson said in an interview. “It’s like jogging; the body doesn’t remember every step, but it knows it has exercised. It has been tuned up. It’s the same idea here: dreams are tuning the mind for conscious awareness.”

Drawing on work of his own and others, Dr. Hobson argues that dreaming is a parallel state of consciousness that is continually running but normally suppressed during waking (except, perhaps when we’re “daydreaming”? -admin).

“Most people who have studied dreams start out with some predetermined psychological ideas and try to make dreaming fit those,”  “What I like about this new paper is that he doesn’t make any assumptions about what dreaming is doing,” said Dr. Mark Mahowald, a neurologist who is director of the sleep disorders program at Hennepin County Medical Center, in Minneapolis.

The paper has already stirred controversy and discussion among Freudians, therapists and other researchers, including neuroscientists.

The Whole Person Phenomenon

Fifteen years ago when I was attending chiropractic college near Atlanta, Georgia, a fellow student shared with me that had doctor had discovered a small tumor in one of her breasts. I asked her what she intended to do about it. After all, we’d just spent two years studying the amazing powers of chiropractic treatment, but there was nothing in what we’d learned that indicated that it had any efficacy in eliminating tumors. She said, to my surprise, that she’d decided to “leave it alone for now,” even though her doctor told her that she was “dreaming” if she thought that the tumor would just disappear.  So, a recent paper in The Journal of the American Medical Association, and reported in the New York Times online, was particularly exciting for me. The paper noted findings, over a period of two decades, that indicated that many small tumors would likely not be a problem if they were left alone, undiscovered by screening. It stated, in fact, that many of these small tumors were destined to stop growing on their own or shrink, or even, at least in the case of some breast cancers, disappear.

“It is becoming increasingly clear that cancers require more than mutations to progress,” said Dr. Barnett Kramer, associate director for disease prevention at the National Institutes of Health. “They need the cooperation of surrounding cells and even,” he said, “the whole organism, the person.” He said that the immune system or hormone levels, for example, can squelch or fuel a tumor.

Cancer cells and precancerous cells are so common that nearly everyone by middle age or old age is riddled with them, according to Thea Tlsty, a professor of pathology at the University of California, San Francisco. She said that that fact was discovered in autopsy studies of people who died of other causes, with no idea that they had cancer cells or precancerous cells. They didn’t have large tumors or symptoms of cancer. “The really interesting question,” Dr. Tlsty said, “is not so much why do we get cancer as why don’t we get cancer?”
