Sightings: Heartland Ghost

I watched this movie on our satillite dish late at night by myself. The movie didn't scare me as much as what was happening while I watched it. During the first half of the movie the volume would come and go. I did not have any problems with any other stations or have any problems before or after. Then I left the living room to go to the kitchen and our stereo turned on by itself. The timer is not set on it and the time is flashing. The remote was on end table and our cat was asleep on the loveseat far away from the remote. NO it did not fall. I was wondering if anyone else had any strange things go one when they watched this movie?!!! Or any other movie??? I am usually one that keeps an open mind but still skeptical. I enjoy paranormal stuff as an amusement.
