The moon and other celestial bodies often refer to one’s high hopes or high expectations. Traveling to the moon would suggest things are in motion towards reaching a high goal you have set. Many moons represent many high aspirations. A half moon may mean you are only giving half your effort towrads that goal. If the moon is very close, you may be getting closer to that goal. Less often, a moon can reflects one’s mood. A bright moon is optimism. A dark low moon can be depression.
