Yeah man... That's some scary shit for real... I used to get it all the time when I was younger and night terrors, but rarely these days.
I would wake up with eyes open but completely paralyzed body and could look around my room and see these dark shadow creatures crawling around my room and sometimes I would hallucinate them holding me down on my bed... Being the cause of not being able to move my body... Shit was traumatizing as a kid haha.
