A pearl diver in a dream represents a royalty, a great person, or a man of authority. Diving into the seawater to catch pearls in a dream means entering into a business with someone in authority, then marrying a daughter from his family and begetting a beautiful son from her.
Seeing a pearl diver in a dream also means seeking to learn about something, or seeking to borrow money from a merchant, or asking someone in authority for an important appointment, or it could mean adventuring into the business of treasure hunting.
A pearl diver in a dream also represents someone who knows the inside secrets of things, or he could be a scholar, a gnostic, a seeker on the path, or an interpreter of the true meanings of the early prophetic teachings.
