Nightmare Fuel / The Midnight Meat Train

Literature Examples:

  • "You will serve in silence", which accompanies the Elder ripping your tongue out and eating in front of you.
  • How about seeing dead human bodies hung up just like any other type of animal meat?

Film Examples:

  • Your everyday life is just a cover for a horrible, horrible secret. You want to be a hero? Good luck: Your life will be turned upside down to manipulate you and exploit your dark tendencies to turn you into a monster who kills random people and feeds them to freakish creatures that live underground. Also, try riding a late night subway after watching this movie and not being... jumpy.
