Ju-On: The Grudge [http://www.wired.com/video/juon-the-grudge/46435411001]
Just from the clip I got scared shitless.
Also, while I'm still on the subject of games, the scene from Indego Prophacy where you had to navigate the female detective though the asylum with all the doors open and the violently insane people are walking all around scared the crap out of me. It's done from a first person perspective and you can only see a few feet, while every once and a while a patient slowly walks across your path making no sound. Utterly terrifying.
