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 his revolutionary theory that dreams were the disguised shadows of our unconscious desires and rears, by the late 1970s. neurologists had switched to thinking of them as just“mental noise”the random byprocts of the neural-repair work that goes on ring 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 these intensely powerful mental events can be not only harnessed but actually brought under conscious control, 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 ring 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 especially active, while the prefrontal cortex（the center of intellect and reasoning）is relatively quiet.“We wake up from dreams happy of depressed, and those feelings can stay with us all day”says Stanford sleep researcher Dr, William Dement.

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 is occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.

At the end of the day, there's probably little reason to pay attention to our dreams at all unless they keep us from sleeping of“we wake u in a panic, ”Cartwright says Terrorism, economic uncertainties and general feelings of insecurity have increased people's anxiety. Those suffering from persistent nightmares should seek help from a therapist For the rest of us, the brain has its ways of working through bad feelings. Sleep-or rather dream-on it and you'll feel better in the morning.
