I fell asleep to find myself standing on an interior wall of a cube. There was no gravity it seemed, though I was, it seemed, bound to walk on it’s surface.
This was not too small a chamber; it stretched almost a hundred metres in each direction, and the isolation or artifice of this situation did not in and of itself worry me. But, after a few minutes of exploration had passed, I noticed that this cube was not as spacious as it had seemed to me at first glance.
I stood at one corner and asked myself “Would it matter me if I was to stand at any other corner?” With this thought I could feel the space I had perceived contract about me. I thought “At this corner, is there any difference between facing one other corner, or any other one?” And with this, and all it’s variations and implications, I felt my freedom disappear, to be replaced with a noose, tightening about my neck.
