Don't be upset - this is complete nonsense. My mother, however, believes wholly in such things, and since I was a small child, has been going on about the 'white witch' she saw twice when she was pregnant with me 40 years ago, and the uncannily accurate predictions she made. To cut a long story short, rummaging through an old bag of family documents when I was visiting my parents recently, we found the notes my aunt had taken of those two 'readings' from the supposed uncannly accurate 'witch' - it won't surprise you (but hopefully will reassure) that, other than having accurately guessed the colour of my father's hair, my mother's marital status (heavily pregnant and wearing a wedding ring) and that her first child would be a girl (50/50), there's nothing at all accurate in relation to the subsequent 40 years.
Wrong number and sex of children, wrong job, wrong predictions about children's careers, travel, illnesses, deaths, etc etc. (Some hilariously wrong mad bits, like that my mother would write a 'racy' Mills and Boon type novel - my mother left school at 13 and has significant literacy difficulties.) My mother had magnified her few 'right' guesses and forgotten all the wrong ones.
I also had my Tarot cards read in my mid-twenties at a particularly low point in my life and was informed (in response to my very specific questions) that I had finished with my education, would never travel again for anything other than a short holiday, would move in with my boyfriend and get pregnant within the year, and would start a business with him. By the following September, I had started a doctorate abroad, and have lived in four different foreign countries longterm since then, have only just got pregnant for the first time fifteen years later, and have never owned or worked for a business of any kind etc.
I agree with whoever recommended Derren Brown's Tricks of the Mind, which is both an amusing read and fun on cold reading techniques. Also look up, as someone else said, interviews with the audience members who heard someone relaying information to Sally Morgan via a microphone.
