The meaning of Heraldry in dream | Dream interpretation
(see Signage, Pictographs)
In the Middle Ages, a person’s coat of arms revealed a great deal, including family lineage, trades, and characteristics. These often appeared on armor so that honors won in battle could be properly attributed (and so you didn’t accidentally kill an ally).
For your dream, consider first what appears on heraldry 7 for more clues. Each item and color symbolizes aspects of you, your relationships with others, your profession, and how all these facets of your life intermingle. Additionally, having an item like this show up in your dream may represent an unfulfilled need to set yourself apart somehow, and make your mark.
