Creepiest/anxiety inducing books?

Hi all! I’m looking for some very unsettling/creepy books. The kind that makes your skin crawl. Not extreme gore but more so creep factor.

For reference I loved Dark Matter (Michelle Paver), Pet Semetary (King), The Ritual (Adam Nevill). I disliked Pretty Girls ( Karin Slaughter), incidents around the house (Josh malerman). Not sure if that helps anyone but just to give some insight!
