The mountain in a dream is a king, a ruler, or a great man of high status and a hard heart. Climbing a mountain is attaining high status and position, but with fatigue and hardship. Descending from it is a decline and loss of position. Sitting on the summit of a mountain is empowerment and victory. Demolishing a mountain indicates the death of a king or the scattering of a group.

The mountain indicates a high position, knowledge, or a place of worship. Whoever sees himself living on a mountain is drawing close to a king or a scholar and gaining protection from him. Water flowing from a mountain indicates continuous goodness from a great man. An unknown mountain indicates worry and hardship.

The mountain is interpreted as a difficult, hard-hearted man. Whoever sees himself fleeing to a mountain will be saved from an enemy and will seek refuge with a strong man. Whoever sees a mountain burning, the king or a great man in that region will perish. Ascending to the summit of a mountain is achieving one's wishes.
