I've been having these awful nightmares for the last two weeks or so and they went from bad to worse. At first it was just language like symbol pattern that clouded my subconscious like a thick fog. On the other side were terrifying images of demons attacking and feeding on my closest of friends.
I also saw a girl I knew that killed herself five years ago for unknown reasons. In the nightmare I saw her, only she looked like she had still been aging as thought she hadn't died. She has blood around her mouth and pooling from her eyes. She kept saying something in a possessed voice. Something that sounded like a warning.
That was a week ago...
Since then I've been seeing her sitting or standing just at the corner of my vision. Just after I would look to where she was, she would disappear. The moment I lost sight of her I would get an intense migraine and see the symbols and her her voice is that haunting voice.
Just yesterday I glanced at my desk chair and thought I saw someone sitting in it. When I looked again I saw Her. She was shivering and held my knife that was sitting next to my bed. She unsheathed it and just as I was forming the words "Don't do it!" she slices a large cut in her neck.
Then I heard her voice, this time in English as she vanishes. Her voice sounds like a sweet whisper in my ears. "Don't stop the fight. Just keep your friends few and close. Be prepared for the coming year."
Just after the voice stopped I felt a searing pain in my head and I blacked out for about two hours.
I think I know what she's talking about "be prepared." I'm not sure I should post what I think she means, but I will be doing some research of my own. That might include... let's just say it ain't gonna be pretty if my theory IS correct. I pray to God that I'm dead wrong. Time will tell.
