Lonesome Dove, Volume 2: Comanche Moon by Larry McMurtry

When Famous Shoes saw Kicking Wolf standing by the mule his thought at first that it was just another of his dreams. Since seeing the white owl come out of the earth he had had many dreams that were not good. In some of them Comanches were killing his children. In another Ahumado had him, and, in a third, a great flood came while he was on the llano. He tried to outrun the water but the flood swept over him and carried him down to where there was a great fish shaped like a Jaguar.

Compared to those nightmares, seeing Kicking Wolf standing by the brown mule was not so bad. Then, waking, he thought he saw Kicking Wolf walking in the white moonlight-it might have been Kicking Wolf or it might have been his ghost.
