In general: If a dream trades of the fact that the dreaming crosses a street, he recognises menacing danger, fear or insecurity. Maybe he braces himself against the majority in or against something which is bigger than he. Psychologically: The dream symbol possibly points out to the fact that the dreaming something meets that he cannot hold under control. If he crosses a field, he maybe has a wrong feeling of security, or, however, he must bring his feelings outwardly. Spiritually: At the spiritual level the Überquerung of a river or a gap often symbolises the death - not necessarily that final step, but maybe important spiritual changes.
