The window in a dream is honor and high status for whoever looks from it. It indicates learning of secrets and the arrival of news. A new window is marriage for the unmarried.

The window indicates a woman who looks at people or a man who spies on his neighbors. Exiting through it indicates falling into heresy.

The window is interpreted as news coming from the direction one is looking. An open window is relief, and a closed one is worry and grief.
