Australia's The Age reports on the strange nocturnal exploits of a middle-aged woman living with a steady partner. "By night, she crept out of their house to seek random sex with strangers. But the woman was unaware of her own double life, which was conducted while she was asleep." The doctor who is treating her, Dr. Peter Buchanan, claims that she is suffering from a rare syndrome known as 'Sleep Sex', which he's hoping will soon be officially recognized as a legitimate sleep disorder. Dr. Buchanan also notes that "Incredulity is the first staging post for anyone involved in this... One has to maintain a healthy degree of scepticism." I think I'm definitely still in the incredulity and skepticism stages, because I'm having a very hard time believing this could be true. I can understand doing things around the house like making a sandwich (or even trying to have sex with your partner) while asleep. But I can't understand how anyone could leave their house, meet a stranger, and engineer a sexual encounter... while being asleep the entire time. I would accept that she may be suffering from Multiple Personality Disorder, but Sleep Sex... I'm not buying that yet.
Update: Here's an article in New Scientist about the sleep-walking woman. I'm still not convinced she was really sleeping. But it mentions a prior case where a man drove 23 kilometres, killed both his in-laws, then pleaded innocent to the murders by reason of being asleep... amazing. Can a person get out of anything by claiming to be asleep?
