Meaning of dream: Galaxy

Dream Galaxy

A galaxy is a bit like a unit of measurement that helps describe the known universe.
It is easy for a modern human being to consider that our solar system is part of a larger complex known as a galaxy and that there are billions of these enormous systems that populate our universe.
To be dreaming of a galaxy is to be contemplating life on this humongous scale.
This could be a literal consideration of existential reality or a symbol for the bigger picture of your unfolding life.
