 Where do entities in the back rooms actually come from? This might seem like a pretty basic question with an easy answer, but you'd be completely wrong. You see, there are tons of theories on this, and since I'm a sucker for all kinds of lore, I'm gonna go over some right now. The first theory is that the back rooms is accessible from other planets besides Earth. And the entities and creatures that we see running around the back rooms, no clip there the same way we did, just from a different planet. The next theory is that the entities were once people, but since they got stuck so long in the back rooms, they turned into this mangrove, distorted mess of flesh that once used to be a person. Or the entities could all be fake, and just in your head from being stuck alone so long in the yellow hallways with the back rooms. Who knows?
