1 Idea: To make a room where all the furniture is covered under white sheets.
I thought it definetly gives the uncanny feeling. Strnage, especially in the late evening and lights coming only from outside. The room should be spacious with a lot of different shape furniture. It also could work with my previous Idea eith the concert hall and the piano. this could be that 'room'.
2. I thought about a bathroom which in no ways is warm, tidy and light.
I think the first idea is the best one. And I'll just start placing things :)
