Murder, suicide, necro, all that good stuff-- but I really like revenge fantasies, or instances where I'd have to "defend myself" so I technically get in less trouble for killing in the instance of an attack. Let the other swing first and then strike back twice as hard. Sometimes I like to think of me disappearing and my body is found in a creepy fashion, and I'm doomed to being the subject of those horrible "Scariest Unsolved Stories" youtube videos.
