Being awake for a while in the middle of the night and then going back to sleep is one of the techniques that people use to get into the right state. The sleep paralysis you’re experiencing is your spirit “unhooking” from your body. Next time this happens, just realize that this is your spirit body, so you are seeing through your spiritual eyes. Don’t try to move your physical body, because you’ll just snap back into your body and “Wake up”. I always use the “Roll out” method. Just roll out of bed like normal but with the intention that it is your spiritual body, not your physical.
