My theory on why so many of us queers love the cosmic horror aesthetic so much is basically that we're all very used to feeling like the universe around us is illogical cold uncaring nonsense with made up rules and arcane ancient rituals.
"Why am I not allowed to kiss other girls?"
"Why is that activity something that only boys are allowed to do?"
We get vague answers like "Because that's how it's always beeeen!" and "It simply isn't done!!!", and fuck me if that doesn't sound like you're surrounded by an alien cult with rules that don't line up with actual reality. Only natural we start to see the universe that way.
