I like that the person who made this created an account called ‘The Exits Are Missing”. It adds to the mystique.
Not too long ago, I learned the nickname for them now is “the backrooms”. Endless creepy empty rooms in a big building. Maybe you’re alone. Maybe you’re not.
I think the new name started from video games where there would be a glitch and the character ends up in a part of the map they’re not supposed to be in and they can’t get out of it.
But it comes out of that kind of nightmare, the one you’re talking about.
