Psychological thrillers?

I have recently watched a non asian movie called 'a cure for wellness'.  I liked it. I was wondering of any of you know any asian psychological thrillers? :)

I don't know if these are the kind of that you're looking for, but maybe check out the synopsis first to see if they fit your criteria?

• Parasite
  
• Cure
• Over Your Dead Body
• Old Boy

Not sure what type of thrillers you are looking for because cure for wellness it's a thriller supernatural, I second the recommendations  By kura2ninja and I suggest also these :

Cure of wellness seemed like a psychological thriller, but I was wrong hahaha. You are right it was a supernatural thriler. 

Thanks a lot for the recommendations!
