Snoozing on your stomach may increase dreams about sex, says a new study. Hong Kong researchers surveyed 670 students, collecting data about sleep postures and dream content and found that stomach sleepers reported more erotic dreams than anyone else. They also described more feelings of "persecution," "being tied up," and "being locked up," reports the Daily Mail. The reason for such reveries? Researchers think it might have something to do with the brain getting less oxygen, which results in the sensation of feeling constricted.
"I believe that the brain during sleep is not at all totally detached from the external world," says the lead researcher, "and stimuli, including those stemming from the environment, are probably incorporated into dream content more often than people observe or are aware of."
