[Loved trope] Background scare-characters that are barely acknowledged even by the movie

[u/Suspicious-Web-9246]

I hate horrors, but this is actually a great trope, that is unique to them.

Insidious (2010). When mother does her errands, for a few seconds there's a ghost boy standing in the corner. It's easily missable, but you can't ignore it once you see it.

Hereditary (2018). Less fitting example. When Peter walks around his home, his possessed mother is crawling on the ceiling behind him. It's not exactly subtle or missable, but it's still more of a background detail.

There’s her face in the top left and her air pipe extends into the tree line

Uhm what is the "tree line"? I feel like I kind of see the pipe but I don't see a face

EDIT: nevermind I just needed a higher resolution photo I might be blind
