Seems to me these nightmares could be caused from watching scary movies. i don't know if you do that. But would avoid them in the future. i had a nightmare after watching "Nightmare on Elm street." i was the girl who was slid up the wall and dropped from the ceiling to a square black hole. i woke up just as i hit the black hole. So I avoid those types of movies since and i don't have nightmares. also ;maybe pray about it and ask for your nightmares to end.you may need someone to pray with you,but you don't have to take my advice either.
