hmm an anime that ive found that founds like you might like is an anime called "Gleipnir" ive seen 4 episodes and its a weird dark one. "Pet" is also a psychological one that kinda takes a bit to understand what the heck is going on but its good. hope this helps :)
you van also check out 'death parade' i think that you should like it

I got you Violet ;)
My recommendations:
-Another (A lot of gore and death, you'll love it if you are anything like me) -Hellsing (Vampires at their best) -Parasyte (freakin' amazing plot and a lot death but it's more of a sci-fi horror then supernatural) -Ajin (Not that dark but has supernatural elements and a great plot) -Psycho-Pass (A lot of murder, it's a psychological thriller) -Neuro: Supernatural Detective (I absolutely love this anime, I reccomend the manga too)

man you GOTTA check out Dorohedoro. It's got all that and more, and I'd definitely recommend the manga over the anime mainly due to the gritty art-style and that the anime isn't finished yet (season one ended in volume 7/23). Don't get me wrong though, the anime's still great too.
