When one dreams of being bitten by a snake he must be treated the same as for an actual bite, because it is a snake ghost that has bitten him; otherwise the place will swell and ulcerate in the same way, even though it be years afterwards. For fear of offending them, even in speaking, it is never said that a man has been bitten by a snake, but only that he has been "scratched by a brier." Most of the beliefs and customs in this connection have more special reference to the rattlesnake.
The rattlesnake is called utsa'nati, which may be rendered, "he has a bell," alluding to the rattle. According to a myth given elsewhere, he was once a man, and was transformed to his present shape that he might save the human race from extermination by the Sun, a mission which he accomplished successfully after others had failed.
