Sleepsterbation 

The act of Sleepsterbation is not under much debate. Although some believe it to be a myth, The truth behind the hidden art of Sleepsterbation lies in the cycle of sleep known as "rapid eye movement" (or REM.) While many can not control their physical movement while in this dream state, some "seasoned veteran's" are more adept at controling basic arm movements such as wiggles or sudden jerks. While not actually masterbating, the sudden jerks or wiggling of the arm causes the practitioner to become aroused and have a nocturnal emission.

Most consider it to be nothing more then a wet dream.

Sleepsterbation is a wonderous thing.
