Not direct abuse but could be triggering. The child expresses that something is happening to her and is told by her dad and sister that it is just her imagination. The child is also terrorised/beat up and injured by the monster itself.
I wouldn't say damaged per se, but a kid has a loose tooth that does come out in a startling way. If you have a tooth trigger, head for the bathroom when they tie a string to the loose tooth & again when they smoke weed.
A patient comes to see the therapist at his house and hangs himself in a bathroom behind the door. The hanging itself is not shown but you clearly get to see the body hung there and then it is mentioned afterwards. They also return to the scene later when the body is no longer there.
Right at the beginning, off screen but still a shocker (the audience I saw it with was audibly upset). If you walk in 5 minutes late or so, you can skip it. And it's very skippable, you will easily understand how this monster works without having to watch that part.
POSSIBLE SPOILERS: 1. After waking from a nightmare, lead character coughs intensely. No v* but sounds could be triggering
2. During a sleepover when the girls are smoking, the lead character starts coughing intensely. She runs to the bathroom and coughs up something over the toilet. I didn’t watch to see for sure if any v* was shown, but the audio was quite triggering to me in a similar was to the electrode scene from “The Ring” if you’ve seen that. Once the other girls rush in, you should be fine
There is a scene with a flashing red cube, Christmas lights flash from red to green for a good amount of time also. Flashes are on th slower side, no strobes.
The monster is shot repeatedly during the scene where Mrs. Billings tries to trap and kill it. No humans are shot at any time, but Sadie is tied up very close to the line of fire.
