A person or an object that has “connections”
(Ring; Bond; Door knocker) In a dream, a link represents the religion of Islam. Holding to the like 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 honor and prosperity of the people of the house.
If one pulls off the door knocker, and if it brakes in the dream, it means that he follows a path of innovation.
Dreams of a link represents connection, networking, interdependence, and integration. This dream may be showing you that you are an important, a vital, irreplaceable link in the chain of humanity.
If you dream of clicking on a link that takes you to a website, you are exploring new terrain, and opening a new portal and dimension of yourself.
