Movies where something creepy is happening in the background not acknowledged by the characters

Was struggling what to google for this but I was trying to think of examples of creepy things in the backgrounds of films. Examples that come to mind in the Dyatlov Pass Movie you can see two creatures move in the background, unnoticed by the characters. Also in It when the librarian is staring at Ben. Basically any examples of something like this where the characters do not notice but an eagle eyed viewer would. And not something like ‘the numbers on this license plate are a reference to this date when something creepy happened’. Appreciate any examples!
