The following video was recorded by a man, who claimed that the doll moved on its own. In order to prove himself wrong, he sets up a camera at 3:08, and leaves the room while the doll is being recorded. The doll lifts its head, and looks at the camera. The uploader mentioned in the description that he believes the doll to be possessed by a demon.
