A few years back. A woman examines her open mouth in a mirror, and sees a couple of fingers sticking up from her throat. What was the movie, and what was the context of the scene?

The Possession.

One night while Em is in the bathroom, she starts to gag. She uses a flashlight and points it into her mouth. After a few seconds, a hand is seen crawling up from the back of her mouth. Em is startled, but doesn’t say anything and goes back to bed.
