I was involved in a group psychometry exercise once, years ago - not something I've done before or since. The leader gave everyone a photo related to his personal life in an envelope and you had to blurt out the first images that came into your head. I saw a woman with dark hair, a curve in a wide, brown river with a muddy shoreline and the sun on the water, then a sort of industrial interior with small metal things going through the air on a belt. They were just flashes but clear, so I described them, feeling like a total idiot. When I opened it, the picture was of his mother, who was originally from Sheffield, who lost another son when he drowned in the river. Maybe the guy was a charlatan but I can't see what he got out of it if so.
