Maybe "My House of Horrors", give it a try if you didn't, check the "Recommendations" and "Recommendation Lists" below its description on NU page for more horror stuff if you want
Camping here I've read some horror novels, but there's rarely any that really scared me. My house of horrors didn't really do it for me at all. Kisaragi Station Arc in DoomsDay Wonderland was terrifying for me, but it's more horror-thriller than pure horror. And Ghost Hunt ofc is my childhood/adulthood/teenage trauma. I love it tho. I can't really think of anything else that scared me
