I've heard of something happening like that before - not entirely the same, but sort of similar. I have a younger cousin, who is nine years old now, I think; one night, my two cousins (her and her older sister) and my uncle and aunt came round to visit. We were all sat in the living room, and suddenly, my younger cousin looked up from the TV and randomly said, "One day I'll live in a house on [insert street name - I can't remember their address] that'll be right on the corner." Wierd thing was, they actually now live in a house exactly where she had described. That happened with my friend, too, when she was young.
