The Bakhtak is a creature from Iranian myth. It resembles a humanoid bear and its name translates to “nightmare.” It sneaks into houses and sits on sleeping people’s chests causing them to have horrible nightmares. It may sometimes go as far as killing its victims and eating their bodies. Citations: Bane, Theresa. Encyclopedia of Beasts and Monsters in Myth, Legend and Folklore.
