If you believe in souls the answer is yes. "Witch" is just an umbrella word, I know some witches who believe in deities, witches who believe only in the energy of nature, and atheist witches. The ones who believe in reincarnation might believe we have a soul and it is reborn. Others see it as simply energy which changes with the lifetime, I have met witches who believe we could be reborn as a rock because they too have energy. Atheist witches believe there is no soul and we just end. No one is right and no one is wrong, you need to do some "soul searching" look within and draw your own conclusions. Myself I believe in reincarnation, we can be reborn an infinite number of times as any living thing from grass, to a bird, and human. Therefore, I believe we have a soul, but I perceive it as a ball of energy and not a ghostly image of ourselves.
