Because the ancients tied benevolent events with the appearance of this planet - Jupiter has associations with grace, charity and positive or productive expansion. This planet also has a special significance to spiritual seekers - who will have this type of dream as the activation of the Buddha/Christ/Wise One Archetype within them. Associated with Jove, Jehovah and Zues, Jupiter can also relate to issues with the father and whether or not one feels protected and cared for by the father. Whether or not you understand astrology, the planet seems to emanate abundance because perhaps, of its size. Dreaming of traveling to Jupiter can be a message about expansion and can portray steps you are taking in becoming more giving of yourself.
