Dreaming of the galaxy is reflective of your creative and uprising energy to express yourself. You feel free and unhindered by any boundaries to convey all innovative ideas and thoughts you may have. The galaxy is in your hands and you want to mold and shape it the way you want. Seeing the galaxy in dreams may suggest that instead of being narrow minded, you are taking a more open minded approach to matters at hand.
Hearing music in your dream could potentially signify your own unique way of expressing yourself. As an art, music comes from the very soul of a person, for it serves as the tool and instrument in how they express themselves. One may not find it easy to express themselves with words, so they turn to another form and method. Music is the singing of the soul, the most melodic of what the heart can say. Dreaming of music shows that inner desire to be free, to be able to tell what is welled up inside.
Having soothing music play in your dream could be an indication of the relaxed and calm state your mind and body is in. However, if the music in your dream is very out of tune and choppy, this could symbolize a time of discontent and imbalance.
