I have got to find the river.

Tunes in my head: Find The River by R.E.M.
Atmosphere: Painful

What exactly is the river?

Could it be a metaphor for one's journey? One could discuss how they walked the banks of the river in order to reach the ocean?

river turns into the ocean, far beyond the undertow

Or could the river be something a lot darker? What does one find at the bottom of a river? Bones?

sleeping underneath the reeds, breathing shallowed and then falls

Or could the river show progress? Constantly flowing. Never stopping. One may not even know of the movement it makes.

waterwheel whirls around, rushing past in perfect time
