Oh for fucks sake. THIS again.
American Indian skinwalkers are medicine men with the deep spirituality of their tribal religion who are shapeshifters. I should know, im an american indian from Red Lake reservation, i seen this shit done before, i seen a man go into a midiwiwin (Medicine lodge) and a bird come out, with the man nowhere in sight. so i assume the same can be for the navajo or ute or hopi or whatever tribe in the southwest, especially the apache are still connected deepely to their tribal beliefs.
