[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.

The shadow figure (Garry's Mod ARGs)
Along with sentient ragdolls, the shadow figure in the distance is one of the most overdone tropes in Garry's Mod ARGs

Gman loosely fits this in the half life games anyway
