No, but Bea meets a boy in the hospital who describes frequently breaking his bones in accidents. It’s not meant to represent abuse at all, but may be triggering to physical abuse victims who were made to say their injuries came from accidents.
No, but an adult man does have to break into a child’s bedroom at one point to retrieve an escaped imaginary friend, and is clearly scared that he will be seen as a predator if caught by other adults
No one burns to death, but one of the IFs is a flaming marshmallow. He’s seemingly not hurt by the flames, though they do cause him to melt a bit, and his eye slides off his face.
During the interview scene, after Calvin tells B not to look at "his eye," she asks which one, he says "you know which one." Then it cuts to the marshmallows eye melting off his face. Safe once you hear dialogue again, and doesn't happen again.
The mother dies from cancer. There is a montage early in the movie that shows scenes with the mother in scarves and head coverings that allude to hair loss from cancer treatments and after that montage, it is clear the mother is no longer present.
Cal and Blue have to walk through a child’s room where the floor is covered in toys, and accidentally kick/step on some of them, but as far as we know none get broken
When the girl first follows the IF into the apartment building and is looking through the keyhole someone appears behind it. It’s not scary but it made me jump.
In an animated kind of way. The most disorienting scene is when the bear tells B to give Calvin a tour of the IF building. The floor flips its tiles over and the walls grow vines, among other fantasy-esque transformation things. All fun :)
Blue has a moment of anxiety when he thinks about his child forgetting him, and has to calm himself down. Later, a businessman has strong anxiety about a meeting, repeatedly telling himself not to cry, SPOILER: until his imaginary friend calms him down.
Bea looks through a keyhole and someone pops up on the other side; this is scored with a loud orchestral sting. There are three instances where Cosmo the detective IF makes a sudden, startling appearance (accompanied by loud brass in the score): the first is in the sequence where Bea is first being shown around the retirement building hallways underneath Coney Island; the second happens in Bea's bedroom, the next morning after a slow ballet scene set to "Adagio of Spartacus and Phrygia" (that one is the MOST startling); and the last happens near the beginning of the mid-credits scene, inside a convenience store. Cosmo also makes an appearance during the interview montage, but it's not a jumpscare.
Light flickers in the beginning that did not affect me, one toy on the ground spins and blinks but is easy to cover on the screen, and during the carnival scene at the boardwalk the lights flicker. That scene is skippable and provides no necessary plot.
There’s a moment in the montage near the start when the mother winks at the camera. Not sure if this meant to be the father filming them or if it’s a fourth wall break
When Blue sees his child, Jeremy, as an adult, he briefly appears to be disappointed that he “let himself go”, before revealing that he actually thinks Jeremy looks great because he’s lost weight since childhood, and mentions that child Jeremy looked “like him”.
Multiple male characters cry onscreen, and while they try to suppress their tears, they aren’t told to stop crying, and the other characters are okay with it.
Someone has an illness and needs surgery. Not much is said about what the illness or surgery are, just something heart related, but they do say that it’s something that can be fixed.
Not sure what the other comment is saying as at the end (vague description) there are montages of some of the IFs finding the thing they were looking for, and it's implied they all got what they wanted in the end.
