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
