--that's weird. Maybe that's a feature of libraries, for the floor to seem to give way like that, for the space between the shelves to seem to grow narrower, the shelves themselves to suddenly reach all the way to the ceiling, so nothing can be seen above or around them.

That's all normal library stuff, right?
