Stairs in a dream indicate the means of elevation in religion and worldly life. Ascending them indicates gaining high status and position, and descending them indicates decline and dismissal. Unknown stairs indicate a long life.

Stairs indicate travel, a servant, or the stages of life. Stairs of clay indicate authority with righteousness in religion, and of wood indicate authority with hypocrisy. Falling from them is failure and loss.

Stairs are interpreted as safety and victory. Ascending them is elevation, and descending them is decline. Broken stairs indicate illness or death.
