Hey,
Okay so I have had this ''nightmare'' a lot, mostly when I was younger and afraid of the dark. But now it's coming back, and I'm wondering if it's not just a nightmare. It starts out ok, I'm just in my study reading, but then the room goes black, and I can't see anything but I know someone is there. (which is weird since I used to always say 'something' was there). Then it skips to when I am saying an exorcism to whoever is there, and it throws me against a wall (That's when I wake up).
If you know what an earth it means, please tell me!! It's freaking me out!!
