This was the scariest moment of Backrooms. Pretty scary movie. I've had this dream 100 times. 1000 times.

It's not captured in this screenshot, but the other part is the partially completed rooms all around. That's another element from the dream.

I hug a wall, cower on the floor, embrace the stairs as I crawl up.

Sometimes it's stairs. A lot of times it's elevators. But always it's all the open space and just the ability to immediately fall to your doom.
