When I moved into a new house(though it was old it was new to me) I would be sleeping and i would wake to hear a faint scratching and the left foot of my bed. The odd part was that I had just moved in and my bed was in the middle of my room. So out of cuirousity I would chec what it was once I was awake it would stop after going for about 30secs and noticed i was awake. Then shortly after ticking would stop my old old TV would turn on every time 5 channels about what I turned it off at. I would turn it off and then TRY to get back to sleep. and sometimes I would triumph. Other times I would a scrathing out my room door(it lead to outside) and i would check and it would be gone and nothing there. I have moved out of that house and am fine now but i lived with that for about 6 years. I am now 15.
