VIDEO: SCARY SHADOW IN MY ROOM, CAUGHT ON CAM!!!

I inadvertently captured a spirit in my house on my camera after letting my dogs outside. After I left the room, a dark image of a 'person' appears and walks into a dark room. Just after that, A picture on the wall starts to sway. I can't explain it. . . I haven't noticed anything out of the ordinary in my house prior to or following this footage (I hope it stays that way). I've always thought that ghosts exist, but I had never personally witnessed anything completely convincing. Well. . .now all I can say is. . .I'm convinced.
