Halloween is a holiday stitched together with religious and occult traditions that span across centuries. The history of this festival originates from the time of Celts, a collection of tribes with origins in central Europe. They used to celebrate the end of the harvest season with a festival called Soin on October 31. The day also marked the Celtic New Year and considered a time between years, a magical time when the ghosts of the dead walked the earth.
