Halloween is a holiday celebrated on the night of October 31..The festival of Samhain is a celebration of the end of the harvest season in Gaelic culture. Samhain was a time used by the ancient pagans to take stock of supplies and prepare for winter. The ancient Gaels believed that on October 31, the boundaries between the worlds of the living and the dead overlapped and the deceased would come back to life and cause havoc such as sickness or damaged crops.Masks and consumes were worn in an attempt to mimic the evil spirits or appease them. Evil Spirits ke?! I reserve my comment!!!!!
