When a women has a wet dream and wonders why she actually had an orgasm without stimulation. The only explanation is that she was Sleepbating. Sleepbating implies that the female individual was sexually stimulating herself unbeaknownst to her own consciousness during a rather riviting dream about a sexy ass motherfucker. This can consist of pleasuring yourself with your hands or by rubbing against your sheets.
Desiree: Holy fuck... did i just have sex???... Nah, i must've been Sleepbating again.
