A desert can symbolize desolation and abandonment, but also a place of contemplation, quiet and divine revelation. Desertion implies that all support has been removed or rejected so the idea of deserting a post, task or friend suggests a sense of inadequacy. Experiencing ourselves as having been deserted signifies being left to our own devices. To dream of being alone in a desert signifies a lack of emotional satisfaction, loneliness or perhaps isolation. Dreaming of being in a desert with someone else may show that particular relationship is sterile, or going nowhere. You might also like to consult the entry for Abandoned.
