My husband's grandfather "came through" her, I guess you could call it. She, in detail, described his home in Alabama down to the sunflower patterns that his grandmother used to decorate the house with, knew his dog's name, and described a picture of him standing in front of the house with the dog that my husband showed to me later. She even told him about the time my husband, as a child, broke his grandmother's favorite table and the grandfather lied and said it was him so my husband wouldn't get in trouble. It was unreal, the things she told him. And he was a skeptic too, like you, and walked away with a new perspective.
