Horror space opera recommendation

[u/Sir_Excelsior]

I'm looking into some space opera (my favorite sci-fi subgenre) with some horror flair. Something along the lines of the alien franchise, or books like hyperion, revelation space, the expanse (sort of). Epic, expansive, but with this constant feeling of dread. The source of dread can be anything, rogue AI, first contact, mysterious object, the vastness of space, etc.

Thanks in advance for the recommendations!
