The desert (wasteland) in a dream indicates dangerous matters or a journey with fatigue. Getting lost in it is confusion in religion or worldly life. Whoever sees himself alone in it will travel alone.

The desert indicates poverty and unemployment or an unjust ruler. Exiting it is salvation from worry and hardship.

The desert is interpreted as travel or a woman of ill repute. Whoever sees crops or water in it will receive good from an unexpected source.
