There are definitely some people who are charlatans and out for money. I myself joined a group of folk who put on a psychic fayre, and heard awful readings, cringeingly horrible stuff, from other readers. Fairies-at-the-bottom-of-the-garden type stuff. However, I did join a psychic development circle at the Spiritualist' Assoc of G.B. many years ago and had some amazing experiences as a result. My problem with it was that I couldn't turn whatever-it-was on and off like a light switch and sometimes it would either not happen when someone asked for a reading, or it would happen at inconvenient and inapropriate times such as at work or on a train etc. The medium who led this circle told me that this was normal. As I had no control over it I stopped attending the circle. I was only willing for it to happen when I told it to. As an adoptee I originally had no contact with my natural parents, but when I did eventually meet my birth mother and recounted my so-called psychic episodes, she told me that my grandmother had this gift. My mother herself did not, and was frightened of it. So - I believe strongly that everyone has the possibility of this gift, and it is up to each individual to develop or forget it. I have no idea how or why it works. I have no idea, really, what it is. I could theorize about it until the cows come home, but it wouldn't make any difference, would it? Derren Brown? I've seen him live and he is truly amazing and I love to watch him at work. We have been to his live shows and his memory is a marvel equal to the 7 wonders. But what genuine mediums do is something completely different.
