Over the centuries people have been fascinated with dreams, their meaning and the way they work. Dreams have been the subject of many controversies beginning with Freud’s theory that stated that dreams reflect an unconscious experience. He also theorized that during sleep, repressed desires in particular those related to sex and hostility are freed. Since at that time the physiology of sleep and dreams was unknown, Freud was left with his psychoanalytic interpretation of dreams that no one questioned until later. The dictionary definition of dreams is somewhat different: A series of images, ideas, emotions, and sensations occurring involuntarily in the mind during certain stages of sleep. Neurophysical evidence states that sleep is not composed of only one type of brain rest, but that it has distinct stages of neural activity throughout the night. EEG waves accompany sleep and are usually high voltage and slow. At about 90 minutes of sleep, several abrupt psysiological changes take place. The EEG becomes desynchronized, showing a low voltage, fast activity pattern that is similar to the way it looks when a person in awake.
