A Dream Interpretation: Tuneups for the Brain
arif says:
“I argue that dreaming is not a parallel state but that it is consciousness itself, in the absence of input from the senses,”
Once people are awake, he argued, their brain essentially revises its dream images to match what it sees, hears and feels — the dreams are “corrected” by the senses.
In a paper published last month in 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. The brain is warming its circuits, anticipating 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. The idea is a prominent example of how neuroscience is altering assumptions about everyday (or every-night) brain functions.
