Wet dreams usually occur early in the morning.

Wet dreams caused by normal biochemical occurrences will be present when the seminal vesicles are full of semen, and an additional burst in the seminal production is observed through the elevation of DHEA and testosterone.

Abnormal wet dreams generally have nothing to do with seminal production. They are a direct result of a sympathetic nervous response to the induced inflammatory hormone prostaglandin E2 and cortisol production during sleeping, while at the same time beta-endorphin, serotonin, and GABA nervous control fails to calm down prostates nervous ejaculation response to the excitation of prostaglandin E2 and Cortisol.
