Words: Waterfall, drift, exchange
Short story(?)

I drift down the river, watching the world around me pass by. Trees and bushes move as the water pushes me forward. I hear a roaring rushing sound, but I ignore it, focusing on the fish in the water, salmon swimming and darting towards the way I came, going up stream as I'm heading down.

Suddenly the water below me was exchanged for air. I'm flying down, falling, watching the watery mist spray in the air. A waterfall, I realize. Time was moving so fast, the world zooming and my life flashes before my eyes but it felt like it was taking forever, then I land, a loud splash sends water in all directions before the boat continues down the stream, no pause to what has been happening.
