No, no I haven't, but I have heard all about them in my religion. I'm a pagan, but I was also raised a catholic. Got the whole religious mixed bag. Catholic and pagan mythos. Spells, herbal medicine, aromatherapy, reiki, shiatsu, the whole nine yards. My family is very Matriarchal. Celebrate the holidays with my parents in the woods. Samhain, Imbolc, Lupenara...so on and so forth.
