(Material aspects)
The landscape in a dream can be an integral part of the interpretation.
It usually mirrors feelings and concepts that we have and, therefore, reflects our personality.
A rocky landscape would suggest problems, whereas a gloomy landscape might suggest pessimism and self-doubt.
A recurring scene may be one where in childhood we felt safe, or may reflect a feeling or difficulty with which we have not been able to come to terms. Landscapes do tend to reflect habitual feelings rather than momentary moods.
