ABSTRACT
The big revolution in understanding dream processes began in 1929 with the development of electroencephalography (EEG), which records electrical activity of the brain. EEG showed that there are different stages of sleep and that during dream sleep, the brain shows vital activity. The progesterone causes tiredness and a decrease in the frequency of the dream stages. Sleep disturbances near menstruation will manifest mostly in difficulty falling asleep and frequent waking, often during the dream stage. Dreaming is dreaming and writing is writing and therefore any attempt to tell of a dream, to turn it into words or to write it, imposes order on the dream and makes it lose its very disordered, associative character, which is made up mostly of pictures, experiences, and feelings. In 1900, Sigmund Freud's book The Interpretation of Dreams was published, in which he presented his viewpoint on dreams.
