Of all the components of a good night's sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated this revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just "mental noise" —the random byproducts of the neuralrepair work that goes on during sleep. Now researchers suspect that dreams are part of the mind's emotional thermostat, regulating moods while the brain is "off-line". And one leading authority says that【T10】______ can be not only harnessed but to help us sleep and feel better. "It's your dream," says Rosalind Cartwright, chair of psychology at Chicago's Medical Center, "If you don't like it, change it." Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep—when most vivid dreams occur—as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system ( the "emotional brain" ) is specially active, while the prefrontal cortex (the center of intellect and reasoning ) is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day," says Stanford sleep researcher Dr. William Dement. The link between dreams and emotions shows up among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are【T11】______ . Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events—until, it appears, we begin to dream. And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs,【T12】______ to control its course. With much practice people can learn to, literally, do it in their sleep.
