I am sorry I did not catch the full picture of your question. I certainly can help you here. My apology for not capturing this in the first post.
The issue with dream interpretation is that the theory or belief system of the interpreter pretty much determines the end result of the dream analysis. However, this particular dream just begs to be interpreted from a Jungian perspective.
In a Jungian sense, your dream is a clear call of the female side of your personality, the amima.
Because men repress (according to Jung) their deeper sensitivities, including most "female" intuition, the anima figure is one of the most significant of dreams for a man.
It is said that when you dream of a female figure, who is giving you an instruction of some sort, that this is your unconscious-sensitive self speaking symbolically. In this case it would be your female intuitive part that does not normally have a conscious voice in your life.
(In Jungian psychology the separation of men and women is simply cultural and we possess both sides equally. It is only through our culture and rearing that males tend to become more aggressive-logical and women more emotional-intuitive. Left alone, they would naturally balance. Jung states that your unconscious is constantly trying to balance these forces and undo cultural influences.)
In this case, your intuitive side, represented by the dream woman, is making you aware of something that you already "knew"...that this other girl is a "match" to your emotional and unconscious self. But because that critical information may have been put aside because of life demands, stress, other relationships or circumstances... it was not acted upon at the time you met her. This female dream figure then becomes a drawing influence on you, asking you to question where you are now, and to draw you into a new relationship with your emotional "match".
The girl you knew in college, Jung would say, is also equally influenced to think of you. Synchronicity, a Jungian view, states that these drawing forces eventually come together in what might appear to be an arbitrary way, but indeed they are purposeful based on the "energy" that you both share. So, simply said. Your dream is a draw to not only enrich yourself through this new relationship, but also a completion of your emotional side. The female figure is a side of you, telling you what you could not act on as a male in normal life. Now that you are acting on it, this dream will most likely not repeat unless you do not establish some sort of rapport with the girl you knew in college.
I hope this response was more of what you desired. It was a fascinating question. Steven
