Cold reading is easy if the target is grieving . Those people who fill a theatre and charge really annoy me. Several hundred people sure as eggs are eggs there will be some who know a Tom,Dick or Harry .
I think some people do have this gift , I knew a woman who was a healer and a medium , I saw her for healing for sciatica, one visit she asked me if I would give an envelope to my husband ,she knew he was in no way a believer but said she had to pass it on to him. I gave it him, it was a rough plan of a narrow country road going over a mountain, not often used, she drew trees, a gate and a X about several 100 yards from the gate, wrote - please check this spot, he read it and dismissed it, about a week later he had to attend court in a town the other side of the mountain, late as usual, the main road had major road works so he and the officer with him decided to take the back road. They passed one car parked on the road side . After court on the way back the car was still there, near a gate with two trees near, it rung a bell and they went over the gate and up the hill, lying a few hundred yards from the gate was a sleeping bag, in the bag was a corpse of a suicide. If they hadn't looked the body may have been there quite some time, not a pleasant thought with the wildlife on that mountain.
