First and foremost apologies for my English, it isn’t my native language!

My question is pretty clear I think but let me explain myself.
I watched the backrooms movie with my little sister earlier today, at the movie theater. Our screening was at 3:25pm, but I somehow got mistaken, and thought it was scheduled for 3:15pm. Long story short, I push the door and quickly realize I’m wrong as I witness a few seconds of the end of the movie. I quickly step back and tell my sister not to enter and go sit somewhere to wait.

This screening ends, and it’s our turn, we enjoy the movie, however, there’s a problem on my end: the scene I’ve accidentally seen earlier didn’t appear at any time.

Once again, it was just a few seconds, but here’s what I think I saw:

a man in a hazmat suit fighting with a thin, black entity (the one we’ve already seen on the youtube videos, and that got popular on the internet) — by fighting, I don’t mean some superhero kind of fighting, I mainly mean he was trying to get away from the creature’s grip

So, I was kind of confused and was wondering if there were different versions or endings of the backrooms movie?

I haven’t found anything mentioning this on the internet, so for now my theory is that I was conditioned into thinking we would see the thin creature in the movie, and when I accidentally caught a glimpse of it, my brain internet the few images it saw with images I already knew.

Thank you for taking the time to read and answering!
