That's awesome, thanks for sharing that. I've gotten to the point of hearing dream sounds like you described while falling through the sleep stages, but it startled me enough to wake me up! I'll give the slight movement thing a try -- which actually reminded me of how Tesla claimed to curl his toes 100 times per foot before going to sleep [1].
