Also known as “Abandoned Office”, Level 4 of the Backrooms is similar to Level 0 in that it is an infinitely stretching office. This level has (fake) windows and blue wallpaper to differentiate itself.
Level 4 is often a level for people to relax, as it has no known entities.
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
