this is a typical Rite of Passage Dream. As one comes into active adulthood, one supposes that one must conform to an exact preconceived model or pattern. This is what one has been taught. Children think this way. but to be open and responsive to Life, one cannot be hemmed in by preconceived expectations. If one is too focussed on expectations then one will miss the actual realities as they have their impact.

In my case, the Man in the Dream told me "Be not one thing, and be not the other". It was an injunction to stay open.

You case adds a certain something. You are explicitly told to seek outside guidance.

In this regards, you should not simply sit and wait for this "Shadowstretcher" or whatever to appear. What I have always found is that one should simply seek out a Guide, just as a means of letting the Universe know that you are active and on the move. If it is an insufficient Guide, then the proper Guide will be along very shortly. Indeed, its become of habit... whenever I find a New Guru, or a New Girlfriend, or a New Anything... I keep my eyes open because as often or not the New is soon followed by a Better. It is as though the Universe is telling me in effect, "If you thought that was good, then check this out".

So, seek out Wisdom and Knowledge. Find a Group to join, or decide on a regimen of reading. Once you act, the Universe will respond with Guidance.
