Your being paralyzed sounds a little like cataplexy. That is, people are supposed to be largely immobilized while dreaming, but in some conditions such as narcolepsy that can happen at other times. There can be a variety of triggers for cataplexy. Maybe in your case lying on your back is one.
It does seem like a good idea to see a doctor.
