White symbolizes the Moon, therefore it is the color of femininity and purity. Dreams which are predominantly white usually bear a positive significance reflecting happy events and/ or the emotional balance one has achieved in the waking life. White is innocence and virtue, delight and cheerfulness, success and prosperity.
White as the dominant color in a dream may also be a symbol for re-birth, revival one is going to experience in the waking life. Also, it may stand for a new perspective on life and world, for a new way of seeing things and changes (most for the better) to occur in one's life.
If we associate this non-color with the eternal white wedding dress, then it may stand as a metaphor for love and a fulfilled long-term relationship. Consequently, such a dream may reflect one's readiness for commitment, stability and steadiness. Moreover, bright white as dream image may represent tranquility and peace of mind, harmony and balance.
