Dreaming about being on an island can have several different meanings and could be very revealing. Consider your mood in this dream. Was the island a place of rest, peace or solitude? If the answer is yes, it suggests that you may need time to yourself for restoration and renewal. The sea or the ocean generally symbolizes our unconscious. Thus, if you were very lonely or fearful of the waters around you, it may be an indication that you are unwilling to look deeply into yourself. You may be afraid of the materials that are under the surface of your conscious thoughts and feelings.
