Thanks for all the suggestions! I've seen some of these films (can't believe I forgot Suspiria, because it came the closest to what I'm looking for. The second and third films didn't get me as much). I'm going to go through the rest asap. Dog tooth never hit my horror nerve but it IS an excellent movie in it's own right. Definitely going to check out Haneke's other stuff, since I really enjoyed funny games, but never bothered to dig deeper into his work. The Last Winter sounds like a more intelligent version of The Thaw, and I'm probably anticipating it the most now, followed by The Ordeal.
Thanks again, and I'm open to any more suggestions!

list of suggestions I've seen for posterity:
- Three Mothers Trilogy
- Dog Tooth
- The Shining
- Cube
- The Grudge (original and american -and yeah, the remake is good)
- Blair Witch Project
