Halloween, rooted in the ancient Celtic festival of Samhain, signifies the end of harvest and the blurred boundary between the living and the dead. Derived from "All Hallow's Eve," it blends pagan and Christian traditions. Marked by costumes expressing creativity and serving as disguises from spirits, trick-or-treating adds a playful touch as children seek treats door-to-door. Jack-O'-Lanterns, carved pumpkins with illuminated faces, ward off spirits and adorn homes. Halloween embraces spooky decorations, haunted houses, and festive parties, fostering a community spirit. Rich in folklore and superstitions, the holiday has evolved into a vibrant celebration that combines ancient customs with modern expressions of fun and mystery.
