heres a random ass backrooms theory for you guys:; the backrooms is a test experiment where each levels have different creatures. scientists from the future capture the creatures and put them into different levels to test what are those creatures cabaple of. To be able to test them, scientist pick a person from any timeline and then teleporting them to one of the levels, not everyone gets teleported to level 0 only, they get teleported to any level so scientist could test the creatures.
