Washaka, The Bear Dreamer
In this story, a young Lakota boy dreams of a white bear that is tied to a tree and bleeding at the neck. His grandfather tells him he must watch for the bear--or something like it. When Little Chief find a white boy tied to a tree, he know this is his "Mato Ska." Based on the dream of Leon Hale, a Lakota man from Cheyenne River.
