Black mirror, killing stalking, obey me, dear door, suicide boy(i guess)

pumpkin night, not sure if it counts as horror but its very gory

not exactly gorey and not bl if thats what youre looking for, but if you want to be on edge the whole time i definitely recommend Blood on the Tracks. if you're looking for bl or yaoi, Feeding Lamb is super short but really fucking disturbing. also recommend Warehouse for bl
