I used to believe that the ghost of Manfred von Richthofen (the Red Baron) haunted my room, namely because my friend and I once got bored and tried to "call a ghost." Naturally, we took it as a sign that Manfred was there whenever something fell in my closet. I used to blame every strange little sound in the night on him, often saying, "Manfred, go back to bed! I'm trying to sleep!"
Once, my older brother and I were home alone, and we kept hearing strange noises--ie, papers crashing in the kitchen--but when we went to investigate, nothing had moved at all. After that, we locked ourselves in his room whenever we were home alone and wouldn't come out until Mom or Dad got back.
Manfred was such a troublemaker. :P
