I’d start by giving each shelf a name that captures the current mood of its contents—like “Serene Reflections” for calm scenes or “Stirred Dreams” for the wilder ones. Then I’d alphabetize those names on the back of each shelf, so even when the layout shifts, you can always find your way by the letter you’re in the mood for. If a shelf suddenly feels “Slightly Chaotic,” I’d add a quick tag “S.C.” on the top corner, and that’s the only label that moves when the reality shifts. Keep the system simple, yet it feels like a living map of your own shifting perception.
