In Erik (2022), the same number keeps showing up throughout the film. Did anyone actually notice this or figure out what it means?

While rewatching Erik on Youtube now, I kept spotting the same number appearing in different places — screens, backgrounds, small details that aren’t called out by the film.

I honestly don’t know if most people catch it on a first watch, or if it even means anything in a concrete way. It never gets explained, and the movie doesn’t reward you for noticing it — which somehow makes it more annoying and more interesting at the same time.

Did anyone else pick up on this?
And if you did… did you come up with a theory, or just give up and let the mystery be?
