(Analogous to Ascending) The elevator in a dream indicates the rapid achievement of goals and elevation. Ascending in it indicates quickly attaining a position. Descending in it indicates a sudden decline.
Source: Ta'tir al-Anam fi Ta'bir al-Manam (Al-Nabulsi)
The elevator indicates changing circumstances. If it is ascending, it is a change for the better. If descending, it is a change for the worse. Its breakdown indicates difficulty in matters.

The elevator is interpreted as worry. Whoever sees himself ride it will be afflicted with worry and anxiety.
