I don’t really get the nostalgia angle as it seems as many of those who are into this kind of thing are too young to have ever been in such a space, let alone worked in one. I’ve worked in a place like this that was well past its prime and though uncanny, it’s certainly not creepy. The illusion of infinitely twisting, identical corridors simply doesn’t hold up when you’re actually in a space like this, but only works…
I'm not sure if that's true. I've definitely been to places that feel intentionally confusing; the basement of my college, several hospitals, etc. Where you walk between two buildings, and suddenly go from Floor 4 to Floor 6, or where you're sure you entered facing north, but after making three right-hand turns, you exit a building facing south.
