Any good recommendations w/o subtitles?
I'm afraid not. I did see a couple of Korean movies that were dubbed and it was horrible, lmao

I'd rather have subtitles than english audio badly dubbed, even though the former is also quite annoying.
If you can overlook the subs issue, there are some really good movies out there.
Some more that I recommend:
A Tale of Two Sisters aka Janghwa, Hongryeon - Korean movie that is more of a thriller than horror, even though it's about ghosts. Very good atmosphere.
Dark Water aka Honogurai mizu no soko kara - Japanese flick that was remade in Hollywood with Jennifer Connelly (haven't seen it yet). Fairly creepy with decent atmosphere.
Shutter - Thai movie that is pretty creepy with some good scenes and a great ending.
The Orphanage - Spanish horror movie with some excellent scenes and a very haunting atmosphere. Very well done.
Saint Ange aka House of Voices - French movie that is slightly similar to The Orphanage and not as good, but worth a watch.
