You are the one who knows better than anyone else what your dream means, but
I'll take a stab at it to possibly giving you some hints.
My perception is that walking hand in hand with a guy you dated represents
the relationship that you were in but he (regardless of who/what caused the
breakup) threw you away which gave you the opportunity to discover the real
you. The bright shining star represents the real you!
We are each a very bright shining spirit, residing temporarily in our temple
- our body, on Planet Earth. So many of us have forgotten this fact and
that may have been a reminder and a suggestion to look for your inner light, if
you haven't begun to do so already.
