Uhh off the top of my head Something Wicked This Way Comes is a favorite read of mine for horror Games? Weird take might be Detention. I like The Last Door (it's pixely but episodic and does the Lovecraft-esque style right). Sounded like you wanted recs that aren't movies so I'll skip those.

Asked my sister for some recs: Visual Novels: Paranormasight (long play time, very good story) Death Mark Games: Voodoo Detective (morbid humor click and point) The Mortuary Assistant (part mortician tutorial, part psychological horror and puzzle)
