According to many scholars, All Hallows' Eve is a Christianized feast initially influenced by Celtic harvest festivals,and festivals of the dead with possible pagan roots, particularly the Scottish Gaelic Samhain. Other scholars maintain that it originated independently of Samhain and has solely Christian roots.
Typical festive Halloween activities include trick-or-treating (also known as "guising"), attending costume parties, decorating, carving pumpkins into jack-o'-lanterns, lighting bonfires, apple bobbing, visiting haunted attractions, playing pranks, telling scary stories, and watching horror films.
