The most fascinating thing about this story was these weird icons every few pages, rendered very approximately from memory:
The girl runs, other people run with her or into her, she goes through a door. Then there's another icon, but subtly different. (E.g., with more rings or fewer rings.) As I recall, the girl had no idea what was going on, which was part of the reason for her panic.
The writing was reminiscent of Bradbury's Frost and Fire in its breathless rendition of panic and fear and running (but a very different subject, of course.)
When you get to the story's end, the meaning of these icons becomes shatteringly clear.
Each icon represents a level of an interstellar starship.
I would have read it roughly in the 70's-80's. My memory is that the story was from an anthology of original SF stories. I looked through most of the ~250 anthologies I have here, but failed to find it. I have lost some books to water and rodent damage, so it's possible the story was in one of those.
