While almost everybody knows about the more common sleep disorders (such as sleep walking or sleep talking), most are unaware that there are much more bizarre things that can occur while you are sleeping, without your knowledge. People with NREM disorders (such as sleep walking) can in some cases have higher exhibit high motor functions in their sleep. Individuals have been documented walking, talking and even driving during sleep. But in a more unusual case, in 2004 a woman in Texas had sex with FIFTEEN complete strangers, ALL WHILE SLEEPWALKING AND WITHOUT HER KNOWLEDGE! (click here to read).
Sleep sex (or sexsomnia) is a NREM parasomnia in which people engage in various sexual acts, while they are still asleep. In many cases, individuals who suffer from sexsomnia, can commit acts that would be considered sexual assault if they had been commited consciously. Below is a clip I found that sums up the disorder pretty well.
I love how the above video noted that men were found engage in sleep sex more than women......Why does that not surprise me?
