At this point, nothing will get you to change the position you've been sleeping in your entire life. Except maybe THIS. According to a new study by Shue Yan University in Hong Kong, sleeping on your stomach makes you most likely to have SEX DREAMS . . . especially DEVIANT sex dreams.

The researchers found people who sleep face down are much more likely to have dreams about sex. Their sex dreams would also incorporate things like being TIED UP and RESTRAINED more often than other people's.

The researchers behind the study aren't positive WHY sleeping on your stomach gives you sex dreams . . . but they think it might be because you get less oxygen in that position, which messes a little with your brain.
