I was about 6 years old when this happened to me. It was a normal night and cold in the house that we stayed in, as usual.
Because I was so young, my mother allowed me to sleep with her in her bed. The way the master bedroom was set up, you could see directly into the bathroom from the bed. Even though I was young, I remember this as vividly as if it were to have happened yesterday. I was in the left side of the bed deep in sleep when a thump coming from the bathroom woke me up. I opened my eyes and at first did not see anything. I looked over to my mother who was still asleep and cuddled closer to her. As I started to doze off again something caught my attention from the corner of my eye, I snapped my head quickly towards the bathroom and saw a jagged movement of what looked like a human form crossing in front of the bathroom door.
It was odd because it was not a smooth movement from one side to the other, it was almost as if someone was hitting the play and pause button repeatedly on a VCR or something similar.
I was too scared to move so I stared into the bathroom watching this figure move back and forth repeatedly. It got to the point where I was trembling and because I had gotten so close to my mother, I had woken her up. She asked me if I was cold (she was still half-asleep). When I did not respond she woke up entirely and noticed my trance like stare into the bathroom.
Because I appeared to be so scared, she moved into the living room with me where we pulled out the sleeper sofa and there we spent the rest of the night. I never told her what happened until I was about 14 or 15, and by then she did not remember that night.
