Halloween's origins date back to the ancient Celtic festival of Samhain, when it was believed the boundary between the worlds of the living and the dead become blurred. It has since evolved into a holiday when spooky legends, myths and folklore take center stage.
Through costumes, stories and celebrations during the Halloween season, mythical beings, from witches to zombies to werewolves all come to life. And each of the season's creepy beings carries its own dark history.
