Billboard Dream

This morning I dreamed I took a trip to a friend's house out in the country and discovered in place of the house a huge billboard-sized drawing of the house. I started crying thinking the house had been leveled. It turned out the house was there, behind the billboard, but parts of it had been relocated to two other buildings on the property. One of the structures was a modern sixties-style house which, when I was inside, seemed to have no walls. I wondered about security, but it turned out the walls were white and everything else was dark and they had seemed invisible at first.
