I had one recurring nightmare as a child: I am standing in the dry bed of a creek looking upstream, the sun shining and the stones warm on the bottoms of my feet. Suddenly, a roaring wave rushes toward me around a bend and I have no choice but to be swept along with it. The water drags earth from the river banks until it is so thick with sediment it has turned the color of Swiss Miss.
