Disturbing, but thought-provoking?

I'm looking for weird, possibly disturbing books. I like alternate realities that are pretty similar to ours except something isnt quite right. I like sci-fi and dystopian futures, I like futures that are so far into the future that humanity has regressed to being less digital. I like unlikeable narrators, or characters in general who are kind of messed up in the head and do horrible things. I like horror, but I dont want gore for the sake of gore, I want it to be thought-provoking. I do like spooky shit, but especially if it has a scientific/psychological element to it.. any suggestions? 😅
