Medium, one of the few I've ever met who seems not to be a fraud. I came under false pretenses, asking her to talk to my dead mother (still very much alive) and dead daughter (never had kids). We'd never met, and this is over 1,100 miles away from where my entire family lives.
She tried to contact them for a bit, went all funny, and then said "Your mother is fine, and I don't think you have a daughter. I do have a message from someone on your father's side, though. A grandfather or an uncle maybe." She proceeded to describe someone who looked like my father's older brother who had just died a couple of years ago, and says the message was (and this is almost word for word, it is burned into my memory):
"You know, I'm not a tennis shoes kind of person, but you could have dressed a little better for this. Now, listen: you're like me, you want to know about everything. This interest in religion skips a generation though, which is why you can't talk to your parents about the things you're learning. but you're making yourself sick and worrying over nothing. You've got to stop studying so hard and get out in nature more."
To put it mildly I was confused, because I knew nothing about him and never thought of him as a particularly studious person; he supposedly repaired typewriters, fridges, etc. for a living and the way my mother described him when I asked he was very close-minded and provincial.
But after this, I called her to ask about what had happened, and she sounded more than a little spooked out. She told me he used to say "not a tennis shoes kind of person" a lot in the 70s because he disapproved of my father and said uncle playing tennis, thinking it was elitist and effete. And, as it turns out, he actually was into the study of religion quite a bit, but in a rather narrow way. Although Jewish by upbringing, she says he converted to UU late in life, and was absolutely obsessed with this book whose title I forget the name of that was trying to explore Jewish mysticism.
So...yeah. I don't know how else to explain this. There are only two explanations: either this lady is the real deal, or there is some demon that just happens to possess her, is able to read minds AND knows my family history, and specifically put these words in her head when she was in trance for the sole purpose of messing with my head.
Make of this what you will. Me, between this and my girlfriend's accounts of drawing Buddhist hells at age 3 with herself in them and scaring the shit out of the local bonzes, I'm convinced. I'm sure there is a scientific explanation for all this; it's just not a branch of science we've explored well yet, is all.
