I am in the mood for several things:
Horror that explores the depths of the unknown -- be it space, the ocean, or even more unmarked terrains on Earth. I just love reading and writing stories where people stumble upon something no human should ever stumble upon and find out truths no one should ever know. Kinda tied to existential horror but without all of the negative nihilism that might come with it.
And Noir -- I love Noir, especially from the 1980s. There's just something so thrilling and exciting about people solving mysteries, murders, and whatever while having some chill 80s music playing in the background. Add in some mobsters, and you got me hooked
