History
Some of today's popular celebrations associated with Halloween have pagan roots stemming from the ancient Celtic festival,  Samhain. This harvest festival of the Druids ushered in the New Year, beginning on the evening of October 31, with the lighting of bonfires and the offering of sacrifices. As the Druids danced around the fires, they celebrated the ending of the summer season and the beginning of the season of darkness. It was also believed that at this time of year the invisible "gates" between the natural world and the spirit world would open, allowing free movement between the two worlds.

If you  participate in Halloween, then you agree with it.
