I was in the cityhall of the city I grew up in. The marble staircase that lead up to top floors with the mayor's office and the library was "as I remembered it." When I reached the top though, everything was different. It had been remodeled and everything had been lavishly redone in expensive marble. Curving corridors led to more curving corridors like a maze. I turned a corner and was promptly lost. I found myself in a dusty museum, the kind with interactive displays that made use of sunlight and shadows and tricks of perspective. (I think) I met someone while studying one of the displays cut into the wall. But I don't remember who it was.
