A fence around the fire

I had a dream last night that I met a man and was flirting and he seemed very interested. (this is not anyone I really know, just someone my dream made up.)  I reached and held his hand and he held my hand and looked at it first happy then seeming disturbed. He looked frustrated and hurt, he left.  I asked someone why he was acting that way and the person told me that he is married.  I knew then that he and I obviously couldn't be a couple but for some reason I thought it was still okay not just to flirt with him but to tell him that perhaps we could still hug, cuddle, sit close, and such things as long as we had certain limits. We couldn't go too far.  So we did sit close and hug eachother and in my dream I thought that was okay since we were not going to do anything more.  I even thought it might be okay to kiss him, I couldn't ever marry him since he is already married and therefore couldn't do certain things, (I think you know what I mean).  I still felt that within certain limits some affection and closeness was ok.  When I woke up of course I know that had this been a real situation those actions would be sin even if we didn't "go all the way". 
I reflected on my dream and I think that it can be a metaphor for just about any sin for anyone.  Flirting with sin.  I then remembered something Father Brian Larkin once said to me during a confession a couple of months ago.  I can't recall exactly what he said but the basic idea of what he said was this:
A tribe might gather around a fire and the children might like to play near the fire, which is dangerous. The adults then put up fences, barriers, or marks that the children can not pass so that they will not get too close to the fire.  The mark they can't pass might be 5 or 6 feet away from the fire. While there is nothing intrinsically evil about standing 3 or 4 feet from the fire, it can be dangerous. 
There was more he said, it made more sense when he was saying it. The basic piont and what he was telling me was to "avoid the near occasion of sin."  Which is something we pray in the act of contrition at the end of confession.  Certain things may not seem sinful but we know that we are getting close, we are pushing the limits, sometimes that can lead to sin.  Sometimes perhaps it doesn't seem sinful but perhaps it is, perhaps pushing some of those boundries is a disobedience to God even if we never touch the fire.

The situation this dream reminded me of, the situation I went to confession about in the past, is in the past.  I don't have this situation in my life anymore (I hope), so I am not sure why I dreamed this. Perhaps becuase I still think of it at times and perhaps need to understand this more deeply.
