Inspired after watching the episode 'Dreams' from the Netflix docuseries 'The mind. Explained'.

Based on the existing connection between the stars and planets' movements and the human mind, experiences and evolution. 

It reflects a contrast amongst day and night, all in the same plane to represent that dreams not only occur while we are sleeping. The planets portrayed balloons, represent an analogy within the functioning of the human mind and the functioning of the universe. People represent fear and falling into what seems like a parallel world.
