Halloween folklore is rich with traditions and stories that date back to ancient times. It is believed to have originated from the Celtic festival of Samhain, where people lit bonfires and wore costumes to ward off ghosts. This festival marked the end of the harvest season and the beginning of winter, a time when the boundary between the living and the dead was thought to be blurred. Over the years, Halloween has evolved, incorporating various customs from different cultures. The practice of trick-or-treating stems from medieval traditions, where people would go door-to-door asking for food in exchange for prayers for the dead. Today, Halloween is celebrated with costumes, decorations, and festivities that reflect its diverse folklore.
