Practicing Wiccans/Pagans Only?

When I was wiccan, I really did not believe in a god or Goddess per se, it was more the power or magic I was after. I guess I was leaning towards atheistism, so the magic still worked anyways. I was a black witch by the way, trying to fight ghists in my house, what a laugh that was. My housekeeper who was voodoo was even more fireghtened then I was, her magic didn't work either. But when I cast spells on people, it worked, so this tells me that ghosts are not dead people. Ghosts are demons. You decide.
