When you first come to a place that you are not familiar with, you immediately get a certain impression of that space. Visually you organize the things you see and give them a place in your experience. Time passes, you make things in that room, look outside, have conversations. Then suddenly you think back to the moment you first entered that space, and you realize that everything in the course of that time has literally and figuratively stands in a different perspective. At that moment the room "folds around" and you have  a completely different view on that same space.
