- The double dose of Body Horror that is the bathroom scene, courtesy of witnessing Angela's reflection ripping off its own jaw with its bare hands, and seeing the same thing happen to Angela herself.
- The Jump Scare when Ben sees the reflection of Gary Lewis's dead body at the morgue is quite disturbing.
- The scene where Amy finds her son talking to himself/his own reflection is eerie enough, but when he turns to get his things and his reflection stays in the mirror, staring at her, is truly hair-raising.
- What Anna becomes when she goes back to the mirror room.
- What Anna went through during her days at the psychiatric hospital. Consider that if this were Real Life and not a movie where Demonic Possession was real and possible, this would be a case of a Mad Scientist experimenting on a helpless, mentally-disturbed young girl—ostensibly to try and help "cure" her, but even if his motives truly were altruistic and not just For Science!, his methods leave a lot to be desired. In the movie the results are bad enough, with his unleashing the demon into the mirrors resulting in almost all the inmates killing themselves and each other, but in Real Life it would result in the kinds of trauma not seen since the days of Bedlam House and electroshock therapy. Worst of all is that while in Real Life it is arguable whether the victim of such mental illness would be aware of what they were doing or what the doctor was doing to them, Anna would have been aware of and experiencing it the entire time.
- Ben's fate.
