Strange encounters of the alien kind have more to do with sleep disorders than little green men with a penchant for kidnapping, according to a study. A survey of people who believed they had had contact with aliens showed they were much more likely to experience sleep paralysis, a state where people are temporarily stuck between sleep and wakefulness and unable to move.
