(Psychological / emotional perspective)
Psychologically, without the ordering of information that we receive, our minds can simply become a jungle of information. We need to use logic to apply order so that we can make sense of ourselves and our environment.
To be trapped in a jungle indicates that we are trapped by negative and frightening feelings from the unconscious, perhaps from those areas which could be considered to be uncivilized.
To be conscious of having come through a jungle would indicate that we have passed through, and overcome, those aspects of our lives which we have never dared approach before.
