(Psychological / emotional perspective)
The image of a journey is a very potent one in dream work.
Any time the idea of a journey becomes apparent, it is to do with the way that we carry on our everyday lives and how we move forward. Every step that we take towards understanding ourselves and the world we live in can be pictured in terms of a journey, and the dreams that a person has reflect that movement. Making a long journey, for example, suggests leaving friends and family, as would running away to sea. Making a short journey would be investigating an idea or principle in the short term.
A difficult journey now behind us means we have come through the difficulties and set-backs of the past.
In our ordinary everyday speech we use idioms to suggest our understanding. We speak of the ups and downs of life, of being at a standstill and so on. Each moment is totally unique, and that uniqueness is reflected in our dreams. Mostly dreams are about the here and now and give a snapshot picture as to what is happening at this particular moment, on our individual journey and are therefore a rich source of information as to our psychological or inner state.
