Watched Perfect Blue recently, bit rough due to its content but good.
Looking for some Hexbear approved suggestions of similar anime.
Mononoke (not princess Mononoke) is paranormal horror but it’s still partially psychological because of that. The art is fantastic and adds to the overall atmosphere and sense of paranoia and claustrophobia, it’s one of my favorite shows.
I loved what I saw of Mononoke, but I really wish they’d put out a version without the paper filter over everything. For some reason it really bothers me whenever I try to watch it. It’s probably just me, though.
higurashi isn’t really this in the anime, but it’s still got some good paranoia going on
the vn has some incredible psychological horror, despite its reputation
If you enjoy the realism/grounded nature of the movie, it’s gonna be hard to find similar shows in anime, especially nowadays as everything is just romcoms or fantasy. Movies tend to be have more options in that category (check out the director’s other works).
In addition to Paranoia Agent, I would say maybe check out Monster? It’s a 60 something episode show about a doctor who saves a child’s life who turns out to be a serial killer, and now the doctor has to come to terms with killing him ‘for the greater good’ as someone who’s supposed to save lives. I haven’t finished it, but it also deals with nature vs nurture and some other stuff.
There are some genuinely creepy stuff in my opinion. I never liked the outro as a kid because I would be too scared to sleep lol.
Everything by Satoshi Kon. Millennium actress, paprika. Might not fit the exact genre but you’ll prob like them
