It may be some kind of "wake up" mechanism.
Perhaps the mind uses some kind of system to test which point in the sleep cycle the body is in, maybe trying to assertain if it is time to wake up and face reality. Generally REM is going to occur when we are at a stage in the sleep cycle closest to waking. Perhaps intense physical dreams are more likely the later we sleep in. The mind starts charging the nervous system with more and more intense signals, testing or perhaps waiting, for the body to reach a weaker, less inhibited state, at which point the physical body responds to this nervous system bombardment, and reacts in a dramatic movment enough way to wake us up.
Just a random theory really, but it could be a mechanism to override the lazyness of us little hairless monkeys wishing to sleep in longer than is good for us.
