What is the theme in Fools Crow by James Welch?

Dreams are a central theme in the story. Fools Crow is a story of dreams, honor, loss and changes. It is a coming of age story that takes place amid hardships beyond anything the Pikunis have faced in the past. Dreams foreshadow and predict the difficulties to come. White Man's Dog has a dream of a white-faced girl, while Cold Maker visits Fast Horse in a dream. Both dreams warn that the group should not continue on to the raid on the Crows.
