To see your own marriage or that of people you care for in a dream is a good omen and foretells happy events to take place in your waking life soon, about prosperity and success in all undertakings.
Marriage may also stand for great changes to occur in one's life, all of them for the better. Therefore, marriage announces improvement, progress and evolution in one's life. You may be going through a transition or developmental phase in the waking life.
On the other hand, marriage stands for commitment, stability and steadiness. It also stands for emotional balance and a general equilibrium which has been achieved or will be soon in one's life.
Marriage, as the union of the masculine and feminine, may also represent the yin and yang, the harmony of the opposites, the animus and anima of human psyche. Animus and anima are concepts of C. G. Jung's theory on human psyche - he stated that anima stands for the feminine inner personality and all feminine attributes present in a male's subconscious. The animus represents the masculine inner personality and all masculine attributes present in a woman's subconscious. According to the famous psychologist and psychiatrist, all men bear a feminine aspect in their psyche and all women have masculine attributes buried in their subconscious.
Consequently, to get married or assist to a marriage in a dream may represent, depending on the case, the fact that a woman has accepted and integrated the animus in her personality or a man has done the same thing with the anima in his psyche. Marriage denotes the union and balance of masculine (yang) and feminine (yin) energy within one's personality.
We should not forget about the fact that usually the masculine stands for the rational, while the feminine stands for the sensitivity and spiritual side of an individual. As a consequence of this, a marriage taking place in one's dream may be considered a metaphor for the harmonious blending of the rational and the spiritual, of reason and emotions, of 'sense and sensibility'.
