I think I know what you mean... the last time I had that feeling was while reading 'And The Ass Saw The Angel' - Nick Cave.
Try something by John Lindqvist.
The most recent of Stephen King's books I read was three short stories in one book, called 'Full Dark No Stars'. Give that a go too.
You'd be looking for something stark, ambient and psychological rather than merely B-Grade jump scares and gore... Atmosphere. I'm sure I have read something very like that but can't quite remember.
Trying to think of ones that have the desolate unreal quality I'm thinking of. Like abandoned buildings. Like this

Oh, but
Dark Water was creepy. (A film was later made of this by the director of Ring, but I haven't seen it. Come to think of it also read Ring as a book.) Recommend!
