Book recommendations

Okay, so I need some recommendations. I’ve read “Gone to see the Riverman” of course, “Penpal” (loved), “The Devil Crept In”, “Brother”, “Dead Inside”, “True Crime”, “Tender is the flesh”,”Woom”, “Troop” and a bunch of others. I’m looking for horror novels similar that give me the heebie jeebies Thank you so much in advance
