Over the past few years, a trend has been abrew. An underground subculture previously reserved only for the religious and spiritual fringes has suddenly become a widespread social media phenomenon. Occult traditions, based in Wiccan and Pagan religions, are undergoing a resurgence in popular culture. Though sociologists estimate that the number of practicing Wiccans and Pagans in the U.S. is only around 350,000, the Wicca, Witch, and Occult hashtags on Instagram reveal over 4 million posts. Clearly, witchiness is in.
