I've been a closeted horror fan for almost my entire natural life. I say "closeted" because it hasn't been until college that I admitted how much I love these creepy little stories.
When I was little, I both loved ghost stories and hated them. I was so sensitive, so imaginative, that whenever I saw a scary movie it would get under my skin and give me nightmares for weeks. I had a LOT of nightmares as a kid, too. The stories I read and movies I watched were more in the realm of fantasy and fairy tales, although there were always a couple of spooky ones that I kept being drawn to. I was always hyper-aware of scary stories simply because of the way they affected me. The images and ideas stayed with me in ways that fairy tales and fantasies didn't.
Then I started watching scary movies on purpose, and getting really annoyed and frustrated by the way that most of them had unhappy endings. See, I was used to happy endings by then, and it made me angry to invest myself into characters that wouldn't find a way out of their troubles. I don't need everything tied up in a nice, shiny bow, but I'm more interested in seeing people face horrible, horrible things and then use that fear to find some previously untapped inner strength, and then get out of it.
That doesn't seem to happen much in horror. Or if it does, I haven't seen it enough. So I started trying to write stories where that does happen. The more I love my characters, the more I torture them, but I do it because I want to make them stronger. I like the creepiness, I like the dread, but the real reason I'm into horror is because it's so much more inspiring and uplifting--for me, anyway--when a character can find a way out of that.
