Seeing an urn in your dream can hold various meanings. A large urn typically signifies negative implications, suggesting that you may be facing some uncomfortable situations in your life. This could affect your relationships or social standing. On the other hand, if the urn contains water, it may indicate a reservoir of your emotions or feelings. If you see the urn breaking, it could signal the arrival of significant changes in your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Urn" (page 456).
In a dream, each type of urn is interpreted differently. A large urn represents a prostitute. In a dream, a cistern or any large conical jar made of porous clay and used in storing water represents a caretaker, a custodian or a curator, the head of the household, his safe, or his shop. Ifthe urn is seen inside a house in a dream, it represents a rich woman who is always in grief. If it is connected to a water wheel in the dream, it represents a rich man who carries heavy responsibilities and who spends his money on God's path. A waterskin in a dream represents a chaste woman. Drinking from a waterskin in a dream means receiving money or benefits from such a woman. If one sees himself drawing water from a storage tank then pouring it into an urn in the dream, it means that he will take advantage of such a woman. A wine pitcher in a dream means discovering a treasure. If one sees an urn containing vinegar in a dream, it represents a pious and a God-fearing person. If it stores butter or ghee for cooking in the dream, it represents a rich man who hides his wealth. If it stores pickles in the dream, it denotes a sick person. If an urn falls from one's hands and breaks in the dream, it means a divorce. (Also see Pitcher)
