Anime similar to Another?

So, I've just started watching the new anime Another and am really enjoying it.

I was hoping you guys could recommend me some anime of a similar style.

Is there anything out there like it, like dark, mysterious, supernatural, thriller types I guess you could call it.

Maybe its a horror? But its also got good elements of suspense and a mystery you try to figure out too, and all the while crazy bad stuff is going down.

Anyways, lemme know what you guys recommend.

Thanks!
