You can find it on torrents. It's a thai horror film that's all psychological (no gore). Most online versions are subtitled, but it's one of the few horror movies that scared the crap out of me.
It is from the same creator of "The Ring"

Original Poltergeist. My family doesn't think it's that scary, but it freaks me out, so it's probably somewhere in the middle.
