Wet dreams that are more formally referred to as nocturnal emissions entail occurrence of a sudden orgasm, particularly while sleeping. This refers to either ejaculation, in the case of a male, or the wetness of the vagina, for females. These emissions occur most commonly during one’s early years of adulthood, but in certain cases, can also come about soon after the age of puberty. Men may either wake up while experiencing the orgasm or not wake up at all while it happens. So what causes this phenomenon to occur? The answer is simple.
