This is a movie that messes with the viewer's expectations for what is real and what is fantasy for the vast majority of the film's runtime, and the pace is quite leisurely, but there is something mesmerizing about this film. The movie sets up the question as to what is real and what is not very early by showing the protagonist vomiting mud, then going to a doctor who tells her that stress is making her imagine she's vomiting mud. She believes this doctor, and for a good two thirds of the movie she is absolutely fearless because she assumes whatever weirdness she's looking at is a hallucination that will pass. It's a neat trick of perspective, and it pays off when evidence piles up that she's actually witnessing a haunting and she becomes quite believably terrified. Then the movie messes with you again by making you wonder if the haunting is being perpetrated by a 1000 year old mummy or a recently missing college girl; and yet again when you wonder who actually killed the college girl (and once more when you wonder if the college girl is really possessed or just a jerk). This is a nesting box of weirdness, and it's not a jump scare movie, although it does have a few good ones in it. Mostly it's a mood movie, and quite a hair raising one. See if it you want something to make you feel dread, not sudden bouts of fear.
