Years ago, when I was a kid, teen anyway, I read up on oobe and astral travel.
So a few times, I woke to find I couldn't move. Sleep paralysis I think its called.
One time I had the feeling of being very high up, a map of Ireland was below me, looked like one of those satelite jobs. It was kind of misty around the edges of m periperal sight. I was scared and there was someone with me who asked where I wanted to go, and I said home, I want to go home. I could have gone anywhere, I suppose, but then I woke up in my bed. Just before that I heard the voice say Beunos dias, I think. and the feeling of light dissapointment, but supporting..
Another time, sleep paralisis again, and I felt that someone was trying to pull me out of my body, kind of aggresive like. I resisted and got the impression of hands in the air and the 'thought/feeling' angry like 'then stay there!'
Another time, I had a vivid dream where these devils/imps dancing on a hilltop. They didn't see me but I hid in a wood log cabin. They tried to get in, and rushed around the cabin, and there was this big rushing wind. Floors were shaking; the walls, I remember calling out Christ three times, then I woke up.
I'd suggest that if you were to try this again, to call on a divinity you love to act as protector and guide.
It must be someone you have a spiritual connection to. It has to feel real to you. And regardless of outcome or anything else, try and just feel love to the exclusion of everything. this may be difficult but don't push yourself too hard,
Treat yourself to something nice like a facial. You sound like you went through the horrors.
