This is actually my husbands story. It happened when he was 12. His couson and him were listening to the radio on one of those radio's with the dial you have to turn to turn it down or up. They were in his cousons bedroom (where before his couson moved in a previous owner had died, an eldery lady). They decided to go to the living room so they turned the radio up. They were only in the living room a short while when all of a sudden the radio was turned down. They were the only two in the house. They just figured it was the radio station or something so they waited. Nothing happened so they went in to check the radio. The knob was turned completely down. They turned it back up and went back to the living room. The radio again was turned down. They went through this a couple of times and just decided to turn the radio off. They can't explain it. I know this happened because they have both told me the story at different times. Maybe the elderly lady didn't like what they were listening to and or the level of the music was to loud.
