the energy that this man represents was in your personal environment...
you were dealing with it on an intimate level.
he was helpful in the dream, and the fatherly aspect of you was grateful.
your waking life "rejection" of him [energetically] was the cause for his
tears (i believe)... his potential for shared love with you couldn't be.
to have strange vibes which made interaction uncomfortable is a clear sign
that things aren't right somehow -- but fear is a servant to your loving heart,
and love is your true guide [according to my belief structure].
