I am a Spiritualistic Pagan (Wiccan), so yes I have a couple spell books in all honesty. My best friend is who really got me interested in it.
It isn't as if I believe in using it for bad, but I know some of it works, but I wouldn't say it is because of "Magic" I would say it's because of a Pagan belief that states what ever your mind TRULY believes (You have to believe in this 100% with NO DOUBT) that the mind will achieve, sounds cheesy, but it's true from what I've seen.
Anyway, I don't have a shrine, or any means to contact the dead, I have everything I want here living, I have no need to contact them. Though I do love cemeteries and have used ghost tracking devices before, which was creepy, because my friend was using one too and it said "Hello" and she says "Who are you" it or rather he replied "Thomas" she then replied "Where are you" all he said was "Three" and the presence disappeared. We couldn't figured out until we went to the third row of the cemetery and there was a tomb stone that said "Thomas Jennings" (I forgot his last name on the stone in all honesty, but it started with a J, this happened last year ;-; )
Though I would be curious to find out what happened to me in past lives.
