(Ring, Bond, Door knocker) In a dream, a link represents the religion of Islam. Holding onto the likes of a chain in a dream means steadfastness in one's religion. In general, a door knocker in a dream represents the door attendant, an announcer, a messenger, a warning post, or a guard dog. If the knocker is made of gold or silver in the dream, it means honour and prosperity for the people of the house. If one pulls off the door knocker, and if it breaks in the dream, it means that he follows a path of innovation.
