      REM sleep is a part of the sleep cycle when people believe you have dreams. You typically have about an hour and a half REM sleep a night over about 4 or 5 cycles (with a preference for REM sleep towards the morning). I think that these can sometimes be a short as 30 sec, but I guess most of them are longer.
