A dead pigeon, it’s head is removed with scissors

The death is not shown on screen. The camera briefly shows the aftermath (not bloody, just a small furry stillness) but if you're not paying attention you could easily miss what it's showing you.

A pigeon flies into a window, and a character cuts off the pigeon's head with a pair of scissors.

a pigeon is decapitated, but it had already passed away after hitting a window

Lots of ants, also loud fly swarms.

There are no horses in the movie.

No cats are ever seen or mentioned in the movie.

No spiders, but lots of large ants.

marijuana is smoked out of two seperate bongs and a spoon-style hand pipe

Several teens are seen drinking alcohol at a party

Psychologically, yes

yes. once someone's arm is engulfed in flame, another time someone's entire body

there's not exactly eye mutilation but there is a scene in which a character is possesed and his eye is breifly shown very bloodshot and as if it's about ti pop out.

a character very gruesomely slices at their own neck with what looks like piano wire.

Not specifically the teeth, but a character's mouth gets bloodied up pretty badly after taking a beating.

A character has a seizure and injures their face on a desk - it is not a medical seizure, but is rather a coercive supernatural event. However, other characters in the scene believe it to be a seizure

a character breaks his nose

If a head counts.

Not exactly squashed but one character's head gets severely mutilated by an accident involving a utility pole and another character smashes his head on a desk repeatedly.

a grandmother dies naturally in the beginning and it isn't shown, only her funeral. both parents die in brutal fashion

there is a graphic depiction of a child's death as well as multiple of the dead body, including a scene of a mother finding her child's body. there is also another character who mentions her son and grandson's deaths but those arent shown.

Very briefly a clown is shown in one of the miniature sets that the mother makes.

Yes, by several people, though the signs are subtle and extremely easy to miss if you don't know they're there. Random stangers smile at the children as if they know them, very quiet footsteps are heard in the house before the family actually enters, the breath of an unknown person is visible outside the house at night, and in a brief night shot of the house towards the end, multiple people are standing outside the house.

Possession is a central theme of the film as a demon attempts to find a suitable vessel. Several characters are compelled to act in bizarre ways during fits of possession before one finally becomes permanent host to the entity

yes there are apparitions as well as communication with ghosts via seances. there are also evil demonic spirits

There are, but surprisingly only very few. Most startling things were seeing a character getting startled by the soft clicking sound. These didn't even feel like they were meant to be junpscares but many people in the theatre startled the first couple times.

A character drools for a good part of the movie. About 4 minutes worth.

You can hear the child’s head be decapitated in a thud, a character saws their head off and you can hear the sawing and their body drop to the floor.

No vomit is shown, but a couple of characters gag after seeing something disturbing.

No, but a miniature figure is made depicting a hospital/hospice room.

There is a character who died of cancer before the beginning of the movie, and it's briefly talked about.

A central AFAB character shares their body and spirit with a male demonic force. This character wears baggy oversized clothes in order to hide their figure is implied to have conflict over their gender and takes on a male form throughout the course of the film. Whether this is their partly own feelings or exclusively that of the male demon is left unstated.

there is mentions of a character's father who starved himself to death, but this character does not actually appear in the movie.

there is a very graphic depiction of a suicide by decapitation. also someone jumps out of a window and falls to their death. there is also mention of a character's brother and father commiting suicide years before the movie takes place.

There's a fair number of instances where characters self-harm in bizarre ways (think: by possession rather than by volition). Most are graphic/bloody.

When Peter is with his friends under the bleachers, he has an anxiety attack

We watch a character hysterically explain what she's been through during the film, and another character ignores her emotional pleas and clearly blames her.

And how! The main indicator of Charlie's presence is her tic of clicking her tongue. It is repetitive and agonizingly grating.

One of the characters neglect and have a distaste for their child, who is implied to have autism or another learning disability.

While not an extreme case, scenes showcasing the inside of the little tree-house at the end of the movie could feel claustrophobic to some people.

No shakey cam, the camera is ominously smooth throughout.

Not during the course of the movie, but miscarriage is mentioned when speaking of past events.

There is mention of an attempted and failed miscarriage.

there's full frontal nudity but it isnt sexual

No, but there is a mention of a grandmother breastfeeding her grandchild which the mother didn't want, which could be triggering to some.

there is an exchange where a side character refers to something that a disabled character drew as ret*rded.

As far as I can remember there are no black people in the movie.

One of the children shown has social issues. In a classroom scene, the teacher pushes her to finish her test in a way that could draw negative attention to this. Later, the mother yells at her, saying, "are you some kind of idiot," for displaying the same behavior. The same character's art is also called the r word

"ambiguously supernaturally trans" There are no "trans" people in this film.

An important antagonist is in the movie to gain a male body after getting into a female body by accident.

It has a happy ending for the demon

yes, but the character is possesed and revived as a new person right afterwards.

Yes. The car itself is not damaged, but the scene is horrific and a character dies. *EDIT* This site is for people who are upset by certain events in media. If someone has prior fear of/bad experiences with car crashes, this scene is almost sure to feed into that or upset them. THAT is the measure. THAT is why this scene falls into the category of car crash. It is car-accident-related trauma and there are not enough categories to nitpick what exactly goes in. The more informed people with specific fears can be going into a movie, the better.

there is a description of a mother attempting to murder her two children but it is never shown. there are also loud screaming fights shown between mother and son as well as husband and wife.

one child is implied to have been abused by the grandmother, and the other child is emotionally abused by the mother. there is also a description of a mother attempting to murder both of her children but it is not shown, only talked about.

there is blood, dismemberment, naked bodies with body parts missing, cutting, and head trauma shown in hereditary

No characters are shown drowning, but a supporting character mentions that two of their family members (one being a child) died by drowning.

A character appears to be floating but also seems to be getting their neck cut by a rope or wire as they are in the air.

A character has an allergy attack causing their throat to close. It starts small and gets really bad.

No, but there is a brutal death involving a car.
