Door
Quick Answer
The master of the house, a means of provision, or one's spouse.
Classical Interpretation (Ibn Sirin)
An open door represents the gates of provision and livelihood opening up for the dreamer. A closed door signifies hardship, closed opportunities, or the inability to achieve a goal. For a single person, a new door signifies marriage. If a house's door is destroyed, removed, or burned, it portends a disaster striking the head of the household.
