Halloween (holiday)

Halloween or Hallowe'en is a holiday celebrated annually on the night of the 31st of October. Originally a pagan holiday, in modern times the holiday has come to be associated with ghosts, witches and the supernatural. In North America, Halloween is typically celebrated with rituals that include dressing up in frightening costumes and "trick-or-treating": going door-to-door and asking for candy.

Counter to common belief, real supernatural creatures tend to lie low on Halloween, considering the holiday much too "crass".
