Blue moon

I dreamt of a shimmering grey Jupiter slowly rotating around the moon. My view was closely focused in on the planet and the moon; they were almost touching. There was a bright light within them. I thought how Jupiter's close contact with the moon must be what keeps it so cool. I felt a slight confusion in the back of my mind. I didn't think until the dream had ended how Jupiter would be rotating around the sun rather than the moon. But the emphasis of the dream was on the cool temperature and sense of calm and silence. I wonder how I knew that this planet was Jupiter? And where was the Earth?
