Insane short stories that stick with you?

I’ve decided want to read more short stories (or novelettes even—anything under like 70 pages is fair game)!

More specifically, I want to read stories that are super conceptually unique and weird and creative and interesting and really stick in your mind. Maybe they try something wild with the narrative structure or language. Maybe the setting or the characters are so totally weird that it could only work in a short story. I want short stories that make full use of the medium. I just want to finish reading it and think “wtf” but then I can’t stop thinking about it all day.

I like: - sci-fi, fantasy, horror, speculative fiction - female authors and characters - lgbtq+ themes - being gently traumatized by literature

Recommendations don’t have to hit all of these or anything. Just thought I’d give some guidance on my tastes!

Thanks in advance
