please suggest me something that is ACTUALLY cosmic horror

this is a bit of a hard one to nail down, admittedly, but I’ve read all of Lovecraft’s work and am itching for more! NOT just any old story about tentacle monsters, please. I want something that gives off the same vibe, not something that has the same trappings, if that makes sense. cosmic horror. big things beyond human comprehension (the colour out of space was a personal favourite). not just any old story about unpronounceable names (which is all internet searches have given me)
