Something just occurred to me... What makes horror stories be horror stories? My creative writing teacher once told the class that horror stories typically have to instill, y'know, horror into the readers. But here's the thing, I once read Dr. Sleep by Stephen King and nothing about it filled me with any kind of horror. Does that indicate a failing on his part, or just that his brand of horror doesn't really click with me? Yet Voldemort from Harry Potter plagued me with nightmares. Does that make Harry Potter a horror, even though it was clearly meant to be a fantasy series? Is horror subjective? What scares the crap out of one person is just another read for someone else? Vampires snacking on ghosts doesn't scare me, but stories about ghosts haunting the living will definitely keep me up at night. What's the kind of horror that sticks with you versus the one that makes you shrug your shoulders? What does a writer of horror have to watch out for? Basically, what makes horror stories be horror stories? Thoughts?
