To dream of a monk represents aspects of our personality that sacrifice desire and pleasure for a greater purpose. A reflection of restrictions placed on yourself for things that you enjoy in order to regain control, structure, and order. You are giving up something for a greater purpose, or for goals you think are more important.
Devotion to a cause. Piety. Devotion to God or excessive devotion to God. Jealousy of losing that drives you to make powerful lifestyle sacrifices to stay powerful.
Example: A woman dreamed of seeing monks at the top of a tower. In waking life she had spent a lot of time giving up junk food and alcohol in order to lose weight because being skinny was more important to her.
