I had a dream that someone showed me a cube. He/she said that inside the cube was the answer that I sought. All I had to do was open it. I couldn't do it. I just couldn't open it.
I spent the rest of the night and morning making a cube that looked and felt like the one I was shown. A few thoughts occurred to me as I was making it.
When I first laid it out I made it from a flat piece of cardboard and drew out the six sides that would make the cube. I thought to myself: This is a flat piece and when I fold construct it there will be nothing inside.
When trying to look at the cube all you can really see is the shadow. And even that you can't trust.
