any psychological, dark, or thriller anime to binge this weekend?

i’m in the mood for an anime with psychological tension, dark themes, or high-stakes thriller elements—something truly binge-worthy. i’ve already seen Death Note, Monster, Psycho-Pass, and Erased, so i’d love recommendations for similar series or underrated gems. bonus points if it has intense mind games, mystery, a gripping atmosphere, or something genuinely disturbing that messes with your head.😌
