When Halloween was approaching I found myself trying to think if I had ever read a fic that managed to really creep me out. It was hard to think of a few. Scaring people is pretty hard to do.
But to start with, (gasp) some original fiction!
I...don't often (or like, ever?) read horror but on a whim that started off having something to do with listening to the soundtrack for the movie
Nightbreed I became curious about the short stories of Clive Barker. This guy...is nuts. He basically has a tendency to take human flaws and turn them up to caricature in a way that's often disturbing. Not all of his stories will really creep you the hell out unless you have a pretty low tolerance for gore - some of them are almost more philosophical - but one of his more highly acclaimed stories is
In The Hills, the Cities which definitely left me a bit unsettled. I've still not put all my thoughts together about it, but I think it's ingenious in that it manages to be somewhat horrifying without there being any real malice or monsters involved. (Be warned, at the link the story has one or two places with wonky indents that aren't supposed to be there, but meh, it's free.)
A short Harry Potter fic that sets you on edge is
Thestrals, in which James won't shut up with a very creepy nursery rhyme he keeps singing to baby Harry, and Lily has a bad feeling. (The author
wrote out the entire rhyme, which is also brilliant.)
I don't know if there's a single Supernatural fan who hasn't heard of
Red (I've never seen so many comments on a gen fic in my life), but it's amazing and could probably easily be read by someone who doesn't watch Supernatural. It goes in places that feel perfectly suited for SPN but in a way that the show itself would probably never do and couldn't really depict in a way that's as cool as leaving things up to the imagination. There are dangers that are realistic and relatable, and then there is the monster, which has something of a history with Dean that Sam knows nothing about.
The creepy factor of this one is more vague, but I've always loved this
House of Leaves-inspired Star Trek fic
"and this great blue world of ours (seems a house of leaves moments before the wind)". The novel it's based on is sometimes considered more of a love story than a thriller, and appropriately this is too. It's Kirk/Spock, and an example that I want to shove in the face of anyone who assumes that all fic narrated in first-person is crap; Jim sounds like Jim but Jim also sounds intelligent, which is kind of a tough balance to strike with reboot fic.
