this is kiiiiinda similar to the idea i had for a story a long time ago that i'll never write about a universe of nested stories where it's possible to travel up or down the tree, but eventually they go up so far that they find an impenetrable barrier and come to the horrifying realization that their understanding has changed from "all stories are real" to "none of them are, not even mine"
@monorail "real" is relative.
