Incubus alert

Incubus alertFrom MedPage Today:

An extreme form of sleep-walking --—having sex while asleep-- —is probably much more common than physicians have previously suspected...

Doctors and others, including prosecutors, need to take this reality into account, [researcher Colin Shapiro] added. "It's a more common problem than people have hitherto recognized."

"I look at it as one form of parasomnia," he said in an interview. "People walk in their sleep, they talk in their sleep, they drive their motorbikes in their sleep, they eat in their sleep, and they have sex in their sleep."

Sounds interesting, but the results were based on an anonymous Internet survey with 219 responses. That doesn't sound very reliable to me, and I also wonder how people can be so sure that they were sleeping.
