Open to interpretation: Drag Me To Hell

I really enjoyed Drag Me to Hell and strongly recommend you see it, if you haven't. But I'm not here to review it. Instead I want to talk about a possible interpretation.

I started thinking more about the movie after reading this interpretation (via SlashFilm). Basically the guy is saying you can read the movie not as a supernatural thriller but the hallucinations of a girl with an eating disorder. I love this kind of stuff. I wish we saw more of it. He really engaged the movie and used his imagination to come up with a great interpretation.

In that spirit, I also have my own interpretation. Spoiler warning starts... now.
