Dreams

Nocturnal emission orgasms or "wet dreams" or "erotic dreams" are when people ejaculate or orgasm during sleep. These occur during REM (rapid eye movement) phases of sleep, which is the main stage when humans dream. This implies that erotic dreams alone are enough to stimulate men, but erections accompany all REM phases. According to self-report data, as many as 22% of young women may also experience orgasm during sleep, with such dreams being more common in college students in higher school years than younger students. The orgasms experienced were positively correlated with high emotionality, including sexual excitement, but also anxiety.
