Dreaming of living in two universes?

Just woke up from a dream thT was a bit disturbing. I had two "cubes" that were hanging in air. Around tge outside of each were visible smaller cubes. Each one a shimmering metallic blue but if you looked closer each one was a scene that was answering a question on the side of the big cube. Each answer had to fall within certain values but the values were no necessarily numbers. The problem was that the cube on the right was dreamed earlier and both cubes were to answer the same questions but the one on the left had not done as well and it confused me because i knew i had answered those questions. That's when i stepped back and saw the two cubes. I had repeated something that normally one would not do. Then i woke up.
