"While my body was asleep, I think my soul rode on a triangular-shaped UFO and went to Venus," Miyuki Hatoyama, the wife of premier-in-waiting Yukio Hatoyama, wrote in a book published last year."It was a very beautiful place and it was really green."
I have not read her book ("Very Strange Things I've Encountered"), and I'll concede that she may be goofy, but out-of-body experiences and alien encounters are occasional manifestations of the very common parasomnia "sleep paralysis." I've thought of starting a separate blog for this topic, but for now will just note this instance in passing.
