I'm looking for ways to amp up the horror/suspense in my 2nd novel. The title of the thread sums up my question, but I have something a little more specific/hard to explain in mind, so bear with me for a sec. I'm not talking about a real-life fear (intrusive government, nasty company bosses, losing your job, murderers/rapists in the neighborhood etc) or about an "irrational" phobia (cockroaches, etc). I guess what I'm asking is...what types of things creep you out in the sense that they get your imagination running? What types of settings, situations etc give you the willies? Stuff like isolated houses; places where everyone's always happy and perfect and you know something's lurking underneath; stuff like that, those are just examples I've heard in passing but I'd love to get some input as to what creeps out your imagination and why. I'll give my own example to better illustrate my point. I sleep on my side, and when I'm in bed by myself with the lights out before I fall asleep, I can't face the wall. I have to either lie on my back or face the room. Even if there's a creepy looking shadow in the room, I'll still know what it is, but I sometimes get a feeling that if I'm facing the wall, there will be something scary standing above my bed that I'll see the second I turn back around lol. Okay my imagination runs rampant, I'm a horror writer, but you get the idea. So...what types of places, situations and the like cause you to be on edge? When does a twig snapping make you think "oh, it's just a squirrel" and when does a twig snapping make your "there's a monster under the bed" feeling kick in?
