Halloween is a holiday that centers on space and ritual. Most likely originating from Celtic harvest festivals, Halloween is tied to processions like trick-or-treating, as well as history and spatial stories. The holiday celebrates imagined settings, characters, and events. In similar celebrations like Mexico's Día de Muertos, people gather in unlikely places; cemeteries and graveyards become the backdrops to picnics and celebrations. There, families offer flowers and food to deceased relatives as they celebrate history and the lives of loved ones.
