SEX AND DREAMS: DREAM ERECTION
There are two kinds of sleep which alternate four to five times each night:
* Non-REM sleep: brain is relaxed, but body is active
* REM sleep: brain is actively dreaming, but body is relaxed
During REM sleep, a lot is going on besides dreaming, and rapid eye movement is only the tip of the iceberg. In a man, although he is completely relaxed and unable to move even one muscle, one part of his body, the penis, is moving, becoming hard and erect. This is one of the most important discoveries made in the sleep laboratory, and has led to a very rapidly progressing field in the treatment of impotence.
It has been confirmed again and again in sleep laboratories that men have erections in the dream state during REM sleep. Hence they have several erections a night, corresponding with the several episodes of REM sleep. This is called dream erection and is completely automatic, furthermore, most of the time the dreamer is not aware of the erection. Most men will tell you that they experience a morning erection when they are just waking up from a dream.
Why do men have these dream erections? Do they serve any purpose? No one has so far been able to give a good reason;
