At an age of around 6, my brother and I used to make a pallet on the floor in a room that was air-conditioned anytime we couldn't stand the heat. Every time that I slept in this room, I would have recurring nightmares of something standing behind one of the rooms large curtains looking down at me. It was long enough ago that I couldn't begin to tell you what it looked like other than it was human in appearance and that it would scare me awake. Each time being woke by the nightmare, I would find myself unable to move.
One such night, I was awoke by my brother's cries from this same nightmare. When I finally got up I found that my mother was comforting him as he was vomiting in the bathroom stool due to some illness. I was told to go back to bed and as I laid back down I saw, behind the curtain, the figure from my dream point at me and say without speaking "You're mine". Immediately both sides of my pallet flew up around me. Scared half to death I screamed "NO" and hit the sides of my pallet with my fist until the unseen force holding it gave way. When I looked back to the curtain the figure was gone.
I'm not sure at which age I learned of demons, demonic spirits, good and evil but to this day the closest thing I could compare the figure and the feeling of doom to would be of something demonic. Not just in its appearance, but in what I know now to be that feeling of evil. For the longest time, I have put if off as all just a bad dream until recently, my brother was telling me of sleeping in this room, waking and being unable to move.
