Stuff of nightmares
Islamic folklore is full of tales of the Jinn or Djinn, supernatural shape-shifters who can be a force for good or evil. The troublemakers sneak into people’s rooms to cause karabasan (sleep paralysis), and then strangle their victims. Save yourself by reading from the Koran or saying a prayer to Allah. If the entity’s wearing a hat, whip it off quick, and it will be your slave forever!
