Sometimes, when we dream, but are close to waking, a bodily process, like a full bladder, or indigestion, makes itself obvious in the dream.  When recounted, it has a narrative form.  Here, we see the construction, from the raw, non-linguistic material of the P-world, a story, an autobiography.  We might attend more closely to that border in individuals, and take note of how they each individually understand their own bodies to work.  What does the spleen mean to X, the heart to Y?  This is akin to trying to map from the observer’s story about glucose and metabolisms, to the cell’s story about a direction.
