Shy teenager Megan moves to a new town with her widowed mother and quickly becomes the most unpopular girl in high school. But when she starts to communicate with a mysterious mirror, her tormentors begin to meet with a horrifying series of 'accidents'. Is the mirror a reflection of Megan's own inner demons... or has she unwittingly opened the doorway of the damned?
Idk if this counts, but a teenage girl looks at herself in a mirror to put on makeup, then angrily screams "You're ugly, I hate you!" and runs off crying
most of the supernatural sounds that occur when the mirror is present are very misophonia-inducing, though not in the traditional sense. for people with sensory issues, definitely painful.
I wouldn't really go as far as calling it gory, but there is some blood on the movie: stabbings including the opening scene, and a non violent scene where a mirror is covered in blood
