I'm new to the horror genre and I'm loving it! I recently read 'we used to live here' 'haunting of hill house' and 'we have always lived in a castle'. What should I try next?

I have recently discovered this genre and I'm really enjoying it. I avoided horror books for a long time because I get really scared watching horror films. I'm not sure where to go next because I don't want anything truly horrifying / frightening / bloody / gorey. I like things that are atmospheric, unnerving, bizarre and perhaps have an element of psychological unease or unravelling. I particularly like the symbolism and themes in Shirley Jackson's books but I'm happy to read things that have less of that (e.g. we used to live here). I have the rest of the day to chill and read, so I'd love recommendations for a page turner! Because this genre is relatively new to me I don't know which types of books to look for. Thank you
