I believe I was pranked by a poltergeist as a teen. I had a cassette tape player. I know I had left it on my bed. When I went to get it, it was not there. I tore my room up looking for it. I asked my brother and my folks if they had seen it. Nope, nope and nope. I went back to my room to look again, and there it was on my bed right where I left it.
Strange.
