So i dont know if anyone on this forum is familiar with OBE's or some people call it astral projection but i just need some more opinions on this experience.

I was at my girlfriends house and we were sleeping but i thought i woke up at first and she was laying over me and i wanted to get up, well i tried to push her off by tapping her on the head but it seemed like she wasn't responding so i tried to say something. I felt my lips moving like it felt like i was talking but no sound was coming out and for some reason i couldn't breath. I started to panic and tried pushing her off but it was like i had no muscle and i couldn't move her at all, then it was like i blinked and i could breath and move again it was really weird. has anyone had this happen to them before?
