A shaman is a tribal healer who can act as a medium between the visible world and the spirit world. Shamans are kind of a mix between priests and doctors. Like a priest, a shaman is a holy man who represents a religion â in this case, shamanism. Like a doctor, a shaman heals people â or at least claims to do so.
