The term ‘a galaxy of stars’ originally applied to what we now call the milky way. In that sense, it symbolizes a potent part of our own universe, and a concept the magnitude of which is not easily grasped.
Psychological / emotional perspective: A galaxy is a huge collection and thus symbolizes vastness and depth in dreams, and not only one emotional response but many. Since we in dreams are usually observing the phenomena, there is an element of objectivity in being able to view our emotions in this way.
Material aspects: A galaxy of celebrities, in the sense of a group of people, most of whom have some importance in their own field, are perceived as powerful. In dreams, if this image is present we perhaps need to decide what the common factor is between them and how this might relate to our lives. You might like to consult the entries for celebrity, crowd, group, planets and shapes / patterns.
To dream about the galaxy signifies your imagination. It also indicates that you are taking in the big picture and are more in touch with the world and events around you.
