No recon, not nightmares. I'm not a little kid, nightmares aint jack.
What I'm referring to is demons. You know, Angels and Demons? That sort of thing. Ever since I was told a story about them from my Youth Pastor about two years ago, I've been scared ever since. Roughly ever night, I get EXTREMLY paranoid. Now, you may find my "fear" funny, childish, whatever, I don't care. Just so long as you don't experience the better off you are.
Demons, essentially, try to scare the living crap out of you. Happens to me ALLLLL the time. Every night. Last night, the night before that, and probably this night. Oh well, you won't understand until it happens to you. So just leave it at that.
