Weird, uncanny, scary? books

Hi!
I’m on a never-ending search for weird books. And by weird I mean things like, difficult to fully grasp until a second read or with notes, uncanny valley stuff, creepy stuff, ergodic books. Books that make you question yourself, your sanity, that make you feel dread yknow?

Some examples of what I mean are House of Leaves (read), Piranesi (haven’t read), Infinite Jest (haven’t read) and the HP Lovecraft works (in the process of reading currently).

Anything also David Lynchian in nature is a win. Love that guy.

The less known the better, because I already have some of the most famous ones noted (though I don’t mind if you suggest something I already have on my list).

Tysm in advance! I’m just gonna keep this one going to the foreseeable future.
