I was the earth and I was looking out into space and I could see this dark colourless walls at the edge of the universe. I felt really sad like I was alone. Suddenly the walls started bubbling into hexagons and they were reflective so I could see my self. It turned into a mirror funhouse and I could see myself a million times. Then Instead of my own face I saw random peoples faces and they were all sad aswell.

There is a trailer or a video explaining the Google Lunar X-PRIZE Project. At one point in the video something happens exactly like you explained with the

into hexagons

and

random peoples faces

I tried finding the video, but unfortunately I couldn't find it anywhere...
Also if you don't mind I think this will be a SPACE thread now...
