Islamic Interpretation of Dreams (Ibn-i Sirin):

(Despondency; Disheartened; Discouraged; Resign) To experience desperation or to loose hope in God Almighty in a dream signifies polytheism or attempting to commit suicide or committing a sin, though the consequence of such state in a dream may eventually turn positive in wakefulness. Despair in a dream also means escaping from a great danger, or engaging in the activities of the dwellers of hell-fire.
