So was the shelf there the same as he described it? Cause that has happened to me. When I was 15 I dreamt once that I was in a grove conveniently labeled "Grove" with a sign hung on a tree and there were gyspy's sitting around in a circle and elves walking around in the trees in the back. Few days later I went to a ren faire I had never been to and saw a show at the Grove Stage which had lost the bottom half of it's sign at some point. The pirates from the juggling show were hanging out and behind the stage there was a chain mail vendor and you could watch the people in the medieval court dresses walking back over there to see what he had. It was really creepy and yet kind of cool but being familiar with fairy tales I high tailed it out of there and checked the time and date. :P
