(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.
My grandma was near death in the hospital. That night I sensed her at the foot of my bed and believed this was a sign she had passed. Next day or so, I went to the hospital and she was still alive.
If she had passed then I'd be telling everyone this was a ghost and would be convinced of it, but I guess it was just my mind playing tricks.
