First of all, I normally don't believe in ghosts or demons, most of my experiences I just shake off, but this one was very intense, and caused me to stay up the rest of the night and the morning in fear.
It was a perfectly normal day, nothing of interest happened, the day went off and I went to bed, and I dreamt, but suddenly in the middle of the dream, I awoke with a grim feeling. The dream itself was not scary at all, so why I woke up so scared I don't know. I opened my eyes and saw the ceiling above me and on the ceiling was a shadowy man, with an orange light around him, or it. It was a completely black figure, and even though it was so far above me, it felt as if it were right at my nose, and it reached out to me, as if it was trying to grab hold of me. I couldn't close my eyes or get up from the bed, I was stuck in fear. I finally moved my hand, and pulled my sheets over my head and closed my eyes.
I was sweaty and scared, and really didn't dare to pull off the sheets. I was afraid if I rose from the bed, I would be within reach, and he would take me.
After about 15 minutes or so in terror, I finally got the guts to roll out of bed, and spring to the door. I hurried out, and turned on the lights before I left the room, and went for the kitchen. There I sat for the rest of the night and the morning, until my mother came down, at which time I slowly went back to bed, after making sure sunlight could come in and illuminate the room.
I am not sure if this was a real ghost, or just my imagination, but I have never been more scared in my life than at that point. I've had nightmares before, and monsters bigger and more evil looking than that shadowy orange figure, but none have had such a sinister feeling about them.
The shadow has never returned though, luckily.
