Well I dabbled with the occult. Bell, book, chalice, candle and all the rest.
I had a hooded cloak made by a lady who ran an esoteric shop. Turns out she was a witch (or so she claimed). It was a very nice black cloak I have to say. After she closed up her shop she went back to teaching and became the principal of a middle school no less.
I sold the cloak at a jumble sale. Hopefully its found its way to the house of unsuspecting JW's who have been tormented ever since. Mwuaaaaa hahahahaha.
My experience is that there's nothing there except for what you bring to it in terms of your imagination.
If you're superstitious and you believe its going to negatively affect you, then stay away.
Otherwise have fun with it but don't take a mediums charlatanery seriously :)
Booo!
