A Spiritual goal or aspiration is signified in dreams by knowing what our destination is. Destinations such as exotic and faraway places could signify our need for excitement and stimulation, or hopes we may have for the future. Dreaming of trying to get to a particular destination would normally indicate a conscious ambition and desire. If the destination is not known to us, we may be moving into unknown territory, or be attempting something new and different. If we have difficulty in reaching our destination there may be difficulties associated with our aspirations. Also consult the entry for Journey.
