The banner in a dream is a scholar, an Imam, or a brave man who is followed. Whoever sees a banner in his hand will gain honor and authority. A black banner indicates a jurist scholar, and a red one indicates a man of war.

The banner indicates marriage for the unmarried. For a woman, it is a husband. Its fall indicates the death of whomever it represents.

The banner is interpreted as the king or a great man. Whoever sees himself following a banner is following an Imam.
