(Psychological / emotional perspective)
When we first set out on the journey of discovery that makes us grow into capable human beings, we often need clarification of the way that we must undertake the journey.
In dreams this often appears as a map, whether this is an old-fashioned map denoting perhaps out-of-date information, or a computer-generated one symbolizing that others have made the same journey.
The direction we are being shown to take is important: i.E.
Forwards, backwards, left or right and we are often helped by the idea of having a course to follow.
