Not having the sex of your dreams? Change your sleeping habits and at least you’ll be having sex in your dreams.
A new study published in Dreaming surveyed 670 people about their sleeping positions, personality, and typical dream experiences. The results? People who slept face down on their stomach with their arms stretched above their head had more sexual dreams—including affairs with celebs, and even a little bondage.
Researchers aren’t sure why the kinky link exists. But study author Calvin Kai-Ching Yu, Ph.D., an associate professor at Hong Kong Shue Yan University, guesses it could be due to constricted breathing and stimulation, as your private parts are pressed against the bed sheets.
Handcuffs and whips? Trysts with Ryan Lochte? Better get sleeping! But here’s the thing: You can’t just up and switch how you snooze. While changing your sleep position overnight can trigger a change in the content matter of your dreams, Yu warns that if you’re not prone to sleeping face down, the change-up could lead to an increased risk of suffocating in bed, sleep apnea, or nightmares. Discomfort can be picked up by the dream process and become part of the actual content, he says.
For now, try sleeping on the other side of the bed. Last year, British researchers found that people who log ZZZs on the left wake up happier than those who rest on the right. Not a bad trade-off.
