THE OTHER SIDE OF SLEEP: THE MEANING OF DREAMS
THE OTHER SIDE OF SLEEP: THE MEANING OF DREAMSAs is the case with many aspects of sleep research, there is no real answer to the question of why we dream. But what about the content of dreams? Is a dream a subconscious “letter to oneself,” filled with cryptic instructions on how to cope with life? Or is it merely a garbled instant replay of the day’s events, with no structure or meaning? Any answer given by medical scientists will naturally reflect their concept of the origin of dreams. Those who see dreams as a purely physical, biological process will completely discount the significance of content and thus may overlook clues to the functioning of consciousness. On the other hand, those who see them as indispensable keys to personality are perhaps prone to imbue them with far more meaning than they actually contain.That many dreams are connected to the past day’s events is obvious. You probably recall your own dreams in which you rehashed a recent confrontation or replayed characters or scenes from the movie you watched before going to bed. These incidents are usually transformed; they might take place in an unfamiliar house, for example, or a person in the dream might have the face of a close friend but play an altogether different relational role— as a parent or sibling, perhaps. It is these very transformations or associations that intrigue psychiatrists and others, who wonder why the brain bothers to make the changes instead of just replaying the scene uncut, unrevised, and uncensored.*289\226\8*
