Skinwalkers

"There is little documented information about the details of “witchcraft” among the Najavo—or Diné, as they call themselves. What is relatively well known is their term “Skinwalker,” or “yee naaldlooshii,” which means, “with it, he goes on all fours.” This is a reference to the special ability to transform into a four-legged animal. According to most modern descriptions, this seems to be the only real determinant for defining someone as a Skinwalker. While there are many self-published books and websites that offer some insight into this world of Navajo witchcraft, much of the information is obscure and does not provide any sort of real account for how these stories and their details came into being. In Navajo cultural beliefs, witchcraft itself is regarded as a taboo subject because it deals with concepts and objects surrounding death. Therefore, Navajo people are strictly prohibited from even speaking of such things."
