That's excellent news for you. When you get that uncontrollable urge to roll over its because your body wants to see if your mind is asleep. If you ignore the urge to roll over the body thinks that the mind must have gone to sleep and will think that its now time to go to sleep too and your body will enter sleep paralysis. When I come out of a dream to fully waking consciousness and don't move I may be in sleep paralysis and sometimes not.
