I was young, like 10 or so, when I saw a ghost (I think). I woke up in the middle of the night and looked towards my door. My room was light enough from streetlights and the moon that I could see someone standing near the door, looking like they were messing with the light switch. It was a lady in a nightgown, so I said "Mom?". The lady turns around, and she's old. Face all old person-y, and looks completely suprised that I said anything to her. SHe reaches out and starts taking these shuffling steps towards me. I can see that she's talking, or trying to say something, but no noise is coming out of her mouth. I'm trying to shout or scream, but I was so scared my breath is caught in my chest. As she got closer, she jsut fizzled away.
To this day I'm not sure if that was a ghost, or just the remnant of some dream I was having. Freaked me straight the hell out, though. I slept with the light on for about ten days after that.
