			So I take it you've seen "The Mist", that's  usually the go-to when it comes to most of that criteria.  
 
You want to take it a touch further, and want to be actually disturbed by a movie, it's a bit controversial but if you can get yourself a copy of "A Serbian Film", I'd recommend it. Despite its reputation, I think it's actually a pretty well made movie.  
If you know nothing of it - probably best to go in that way.  
Meets most, of your criteria, though it's not supernatural in any way.  
 
I don't know why I feel like recommending this, but you might like "Cube". 
 
As for mindfucky films...existenz? naked lunch? the 13th floor? Not strictly horror though. 
Also try "In the mouth of Madness".
