Nightmares

I wake up screaming, sometimes crying. I simply can't tell which side is lying. Is it me, or is it my brain? I can't deal with much more because it drives me insane. I see visions of horrible, gruesome things. Like people who've been chopped to bits, and little dead kids that sing. I can hear the music playing and it scares me to death. I try to run away, but I get sicker with every breath. I see people I love and others that I've never seen before. If I ever see those strangers when I'm awake, I'll freak out, I'm sure. Why do I have these nightmares each and every time I sleep? Have I not cried enough tears for people I'll never meet? I'll never understand it, but I guess I'll have to deal. It only gets to me this bad because it all seems so real.
