I have been studying witchcraft for over 20 years and I have never cast a spell. Nothing other than the usual "old wives tale" type of stuff, handed down through families. I don't believe in deities, so there is no one for me to invoke, summon, or however that works. My question is, can I be a witch if I never cast a spell? Most of this interest was borne out of a search for answers to why my dreams have always been so vivid and why some of them were prophetic. I'm nothing special. I have no powers. I have no way of conjuring up a dream. They just happen. I simply don't know what I'm supposed to be doing. Please help?
