As a witch, how do you celebrate Samhain/Halloween? in Chit Chat - Public Posted October 11, 2019 Secular Halloween is costume and trick or treat. Spiritual is a dumb supper, divination, offerings, card readings online.Halloween lacked a captivating quality or meaningfulness to me before I began practicing. So I’d really like to try these things out to give the holiday meaning. I’ve read that the Norse celebrated it as “The Winter Nights” and was several days long, and at about the same time as Halloween/Dia De Los Muertos if I’m remembering correctly.
