A childhood belief about monsters

This is not my belief but somehing I told my sister, Serena, when she was around 3 - 4 years old. She always wanted to go outside and play, even in the rain, so keep her from running out in the middle of a rainstorm I told her that rain awoke the dead. I made it quite an enthralling story. Exlaining that it went into their graves and re-animated them. Needless to say, she didn't go out in the rain for a few years. :P
