Dear Dr. Universe,Why do we daydream?Pat Caraher - Pullman, WashingtonWhen I asked Barbara Hammond this question, the original thing she said was, "Who knows?"Barbara Hammond is a psychologist at Washington State University. What she elbow room is that a lot of people have some interesting psyches slightly dreams. tho thats about it. By the time you finish reading this, youll know much of what we know for certain about dreams. Youre about to become a dream expert. superstar thing we do know is WHEN we dream. Thats during a period of sleep called "REM sleep." REM means rapid eye movement. During REM, your eyes are moving more or less a lot even though theyre closed. Your brain is also very busy--and youre dreaming. Hey, Im no Sigmund Freud, but whos a psychologist to turn to when they have a weird dream they want to talk about?Another thing that happens during REM is that your muscles are basically paralyzed. You know those dreams where youre trying to run away from something, but your legs are authentically, really heavy? Now back to WHY. According to Ms. Hammond, there are two sets of explanations. First theres the "physiological" set. "Physiological" has to do with how the body works. Some scientists think perhaps we dream in order to exercise our brains. When youre awake, messages are constantly speeding among all your billions of brain cells to keep you moving and thinking and digesting and so on. So the conception is that when youre asleep, dreams exercise the "pathways" between the brain cells. Personally, I like this idea of exercising while I sleep.There are a couple of things that help this idea make sense. The first couple years of your life are the most intense for learning. Thats also when you have the greatest amount of REM sleep -- which means you probably dream an awful lot.Another thing--your brain waves during REM sleep look about the same as your brain waves while youre awake. (Brain waves are electrical patterns that show up on a machine that measures the brains activity.) During other parts of sleep, the brain waves look very different.Then theres the "psychological" set of ideas about wherefore we dream. Psychology has to do with your thoughts and emotions.Ms. Hammond says that most dreams are actually about immediate concerns in our lives. Some dreams may help us know more about ourselves. Others might be practice for dealing with daytime problems.
