It is said that from midnight on October 31 to midnight on November 1, the God of Death would gather the spirits of those who had died in previous years and have them punished.据说从10月31日半夜到11月1日半夜，此日死神会召集回今年死去人的魂灵，然后让这些鬼受到惩办。
The Celtic people, who lived more than 2000 years ago feared the evening of Oct. 31 more than any other day of the year.
It was the eve of their festival of Samhain. Samhain was a joyful harvest festival that marked the death of the old year and the beginning of a new one.
The day itself was a time for paying homage to the sun god Baal who had provided the people with the ripened grain for use in the upcoming winter.
Come evening evil spirits were everywhere.
Charms and spells were said to have more power on the eve of Samhain.
Several rituals were performed by the Celtic priests, Druids, to appease the Lord of the Dead.
