CALLING JOHN EDWARDS: My dad, who passed away when I was 15, has been making prominent appearances in my dreams lately. He's had the occasional cameo for as long as I can remember, but it seems that the network that broadcasts into my sleeping head has picked up his contract for the season and made him a regular. In my dreams, he's either a bizarre authority figure or an enigma -definitely not the great dad I knew. I wonder what my subconscious is trying to tell me?
