does anyone know any animes in the psycological horror genre

The only horror anime I've ever seen is elfen lied

Another
I'm not sure if it's really the kind your searching for (because there's a bit of supernatural in it)
...but...I think it is..probably

o tu could also like Mirai Nikki o Higurashi no Naku Koro ni

(love all of them x3)

Well since horror is my favorito! genre of anime, here are some that come to mind:
-Higurashi No Naku Koro Ni
-Jigoku Shoujo
-Le Portrait de Petite Cossette
-Another
-Ghost Hunt
-xxxHolic (it has some psychological horror elements)
-Serial Experiments Lain (not necessarily horror but very psychological)
-Shiki
-Boogiebop Phantom
-Monster

Here is the Higurashi No Naku Koro Ni opening. Once tu watch the series, watch this opening backwards. There is a lot of symbolism hidden in it. :)

these are kinda horror/psycological.....

Pandora Hearts
Black Butler
Hell Girl
Ghost Hunt
Ghost Hound (i dont remember it to well.. so mabey not..)

Puella Magi Madoka Magica.....mabey... the wiki says its a horror but i dont think it is at al,l i think it might be a physiological one though...

Another, Elfen Lied and Higurashi...that's all I can think of right now :)
