foxes are supposed to be the souls of witches. In our local stories, it is believed that when a witch goes out, her body lies in bed, half-dead, and her soul goes out as a fox and causes damage.
Von Franz establishes the fox as the exteriorized, destructive soul of the witch across European folklore, linking it to demonic cunning and a tradition that extends into East Asian belief.
