[问答题]Practice 6Why Do We Dream?　　Our dreams may affect our lives (and vice versa) more than we ever realized, says new research. For 11 years, a 58-year-old anthropologist kept a journal of nearly 500 dreams by a man. By analyzing color patterns in the dreams, Arizona-based researcher Robert Hoss could accurately predict certain things about the man’s emotional state. Hoss correctly identified two separate years when the man experienced crises in his life. The anthropologist confirmed that in1997 he had clashed with a colleague over a management issue, and in 2003 he’d had a falling out with a friend that left deep emotional scars.　　How was Hoss able to gauge the dreamer’s turmoil? “The clues were in the colors,” he says. The anthropologist’s dominant dream hues were reds and blacks, which spiked during difficult times. “Even without knowing the events in his life,” Hoss observes, “we accurately determined the emotional states based on those colors in his dreams.”　　Hoss is among a growing group of researchers who, thanks to cutting-edge medical technology and innovative psychological research, are beginning to decipher the secrets hidden in our dreams and the role dreaming plays in our lives. A look at some of their latest discoveries can give us new insights into the language of dreams.　　Dreams are a way for the subconscious to communicate with the conscious mind. Dreaming of something you’re worried about, researchers say, is the brain’s way of helping you rehearse for a disaster in case it occurs.  Dreaming of a challenge, like giving a presentation at work or playing sports, can enhance your performance. And cognitive neuroscientists have discovered that dreams and the rapid eye movement (REM) that happens while you’re dreaming are linked to your ability to learn and remember.　　Dreaming is a “mood regulatory system,” says Rosalind Cartwright, PhD, chairman of the psychology department at Rush University Medical Center in Chicago. She’s found that dreams help people work through the day’s emotional quandaries. “It’s like having a built-in therapist,” says Cartwright. While we sleep, dreams compare new emotional experience to old memories, creating plaid-like patterns of old images laid on top of new ones. As she puts it, “You may wake up and think, what was Uncle Harry doing in my dream? I haven’t seen him for 50 years. But the old and new images are emotionally related.” It’s the job of the conscious mind to figure out the relationship.　　In fact, dream emotions can help therapists treat patients undergoing traumatic life events. In a new study of 30 recently divorced adults, Cartwright tracked their dreams over a five-month period, measuring their feelings toward their ex-spouses. She discovered that those who were angriest at the spouse while dreaming had the best chance of successfully coping with divorce. “If their dreams were bland,” Cartwright says, “they hadn’t started to work through their emotions and deal with the divorce.” For therapists, this finding will help determine whether divorced men or women need counseling or have already dreamed their troubles away.
