Mora or Nightmare

Bosniaks believe that a Mora is a discarded or cheated girl which uses this form to get back at her boyfriend. In her invisible form she comes every night around midnight and suffocates the young man by sitting on his chest. The young man feels a large pressure on his chest, he sweats and has nightmares. He awakes in the morning pale and feels powerless. It is believed that every girl can turn into a Mora if she surrenders her soul to Iblis.
How does one catch a girl-Mora? From the mosque one must bring a green belt used for tying down a deceased to the stretcher during a funeral. The one who is attacked by a Mora must go to bed holding the green belt in his right hand. He mustn't fall asleep but only keep his eyes closed. Around midnight the Mora will appear and sit on his chest. At that moment the man needs to put the belt on himself and the Mora will become visible to the human eye. Caught in a trap the Mora will be scared and she will start to beg the man not to reveal her secret in return she must swear not to be a Mora any longer. That way she will lose her invisibility power and she will become a normal girl once again.
