) Although you do need a certain amount of REM sleep per day to be able to function properly, once you body gets the idea that you will only be sleping for short periods of time, as SOON as you hit the sack, you will go straight into REM sleep, and this way (once your body adjusts) you get the needed amount of this sleep per day.
