As the creator describes:
"The circles are the hours of sleep and time between dusk and dawn. The different colors represent different dreamy experiences and feelings such as daydreaming, dreams of passion, nightmares, navy being night. Plus dreams are always associated visually with being in clouds or bubbles. They go in a diagonal like the path of the moon and sun in the sky, from light warm color of sunset to light warm color of sunrise"
