To see nuns in your dream, signifies purity, chastity and obedience. It also indicates that you need to live up to the vows and promises you have made. Material fortune and gain may be interfering with your spirituality. Consider also the pun of being "none" or "nothing".
If you are a woman and dream that you are a nun, indicates unhappiness with your current situation and environment. You are looking for an escape. Alternatively, the dream suggests that you are looking for a sense of security or calmness in your life.
For a religiously inclined man to dream of nuns, foretells that material joys will interfere with his spirituality. He should be wise in the control of self. For a woman to dream of nuns, foretells her widowhood, or her separation from her lover. If she dreams that she is a nun, it portends her discontentment with present environments. To see a dead nun, signifies despair over the unfaithfulness of loved ones, and impoverished fortune. For one to dream that she discards the robes of her order, foretells that longing for worldly pleasures will unfit her for her chosen duties.
