How To Avoid Unusual Thoughts During Sleep?

ok so i have been told i am moaning very loudly when i sleep, but last night i when i shut off the tv and closed my eyes i am not sure how long i was asleep for , it seemed like as soon as i closed my eyes i couldn t move but i was awake staring at the wall and trying to yell for someone to come help me but i couldn t say the words just loud sounds i felt like i was being held down or just scared so bad i couldn t move. and i have had these pains in my forearms for the last couple of months.
