(Thread prompted by the one about seeing someone with lizard eyes, who is possessed by a demon)
I have once. Waken from a dead cold sleep, my girlfriend and future wife said to me "we're not alone". I looked at the foot of the bed and their was a very angry young boy. I was shocked and became afraid myself as I sensed a power there, and then, like a balloon popping, he vanished.
She asked me what I saw, I said a very angry young boy, who looked to be age 9-10. She confirmed that was what she saw too.
I suppose it could have been an angry guardian angel, or even a passing demon, but let's go with ghost.
I have never doubted things spiritual since that day. I was about age 19.
Yeah, you know I thought about it and his trajectory was from the back acreage moving towards the house and barn. It was near the spot we used for a path because it was along the edge of that particular field. So if you think about it, that's a reasonable place to see something that's happened many times before. It wasn't like I was back in the woods or something like that.
