I actually have to say they do, but as others in this thread, also, not the creatures of myth that turn into mist and suck blood. I have a wiccan friend who was trying to explain something that she believed to me, and it made sense. I personally dont know anyone who is, as she described it, somewhat of an aura vampire. That is, when around certain people, you are energized, or feel like you are drained. It didnt make sense to me before, but, hey, I am an open minded guy, and am willing to think that it is possible.
