Samhain and Halloween: Samhain was first observed by Celtic Pagans and marked the Celtic New Year, the end of summer, and the end of the harvest season. The Holiday signaled the beginning of winter, which Pagans associated with death. It was considered a time when the veil between the physical world and the Otherworld was thin, allowing spirits of the dead to visit the living. Rituals may include dancing, feasting, being in nature, and building altars to honor ancestors. Samhain is the origin of Halloween.
