Aight I got one. When I was about nine or ten my sister, who is a couple years younger, and I shared a bed room. Our beds were caddy-corner to each other, so if you were laying in the bed facing the room you could see the other bed. Im just gonna preface this by saying I had real sleeping problems and I was scared of fucking everything which probably explains what happened.
So my mom made my sister this life sized doll as a craft project one weekend. I immediately hated the thing, the face was scary as fuck and I didn't like something life sized in my room. My sister loved the thing though so I kept my fears to myself and let it slide. The doll slept in my sisters bed every night and I would always fall asleep trying not to look at it. One night I was woken up by footsteps next to my bed, I looked up and there were two figures next to my bed. At first I thought it was my sister holding her doll standing next to my bed so I just told her to go back to bed, but she didn't respond. I turned around to turn my bedside light on, and when I turned back around I was scared shitless. It was my sister and her doll, but the doll was the one standing upright, my sister looked limp in its hands. I screamed and shot under my covers. When my parents came in the room my sister was laying next to my bed with the doll in her hands, fast asleep. It was scary as fuck but looking back I was probably just half asleep and mis saw things. Anyways the next day I ripped up the doll and blamed it on the dog.
