Thank you all for your suggestions. Sorry for replying so late. I haven't had much time on the computer and with school taking up so much time.
I was attacked twice again last night. I tried telling it that it couldn't hurt me, that I loved it and then what I was seeing stopped (I saw the outline of a face coming closer and closer). But I was still paralysed. Then I started feeling extremely heavy and the pain grew worse. The second time it happened, I was 'astrally raped'. After reading your suggestions, when I try them, I hope that I'll be able to project in peace and not have anything stop me or end up paralysed.
And just to add, since I forgot to say so before, my SP attacks (and even my spontaneous projections) all happened right after I moved into my new house. And I began having reoccurring dreams of a demon possessing my little sister and mother (never my father). In my room, the words "Die" and "Die Slowly" are written on the ceiling.
SpiritPathwalker: I looked at that topic. I read your post. I'd love to battle it and I've tried fighting it... problem is, I can't move at all. I can manage my hands and feet (and move my neck sometimes), but that's all. And when I manage to do those, it's only to get out of the paralysis. You know, I have considered that it could be an 'inner ego'. That's one of the reasons I was reluctant to admit that I was being attacked by a neg. But, my SP attacks happened right after I moved into my house. And (if you read what I wrote above), the words 'Die' and 'Die Slowly' are written on my bedroom ceiling.
Tyler: I wouldn't know if it was attached to me. Core images? I've heard of this before but I'm still not sure what they are. Are they images that the neg makes you see (every now and then)? Like, you're just reading a book, when out of nowhere you start seeing terrible things (people killing eachother, etc)? Cause if this is what you mean, then I've got them. ... getting rid of them will be hard. I've got a lot of stuff to deal with emotionally. I'd like to get Robert Bruce's
Practical Psychic Self Defence book, but I'm still trying to find his
Astral Dynamics!
beav31is: Heh. You know, I've actually tried that, telling it to just kill me already. I've tried telling it that it can't hurt me (tried using the conjurations). I've asked it what it wants... But I only end up with more pain

Nita: Hmm. Self-exorcism? I didn't know that you could perform it on yourself. Wouldn't it be very dangerous? And I'm assuming the 'egg method' is explained in the book. As for the burning garlic and herbs, I'll try it when I can. Is there any specific prayer you recommend?
Thanks again for your suggestions.
