Islamic Interpretation of Dreams (Ibn-i Sirin):

(Waterless plain) Seeing a desert in a dream means escaping from difficulty to ease, or bidding farewell to adversities to meet with opportunities, or it could mean repenting from sin, reversing the course of one’s business from loss to profits, or it could mean recovering from an illness.

If one sees himself poor and walking into a desert land or a ruin in a dream, it means his death. Walking through a barren land in a dream means engaging in a futile business or a benign affair. Walking in a plain in a dream means reaching ease in one’s life, receiving honor or engaging in good deeds depending on how far one walks in that plain during his dream.

A desert in a dream represents joy and happiness, depending on how vast it seems and how green are its plants in one’s dream.
