What do you guys think?

The past few weeks have brought with them VERY high stress levels and some odd dreams. I keep dreaming that I am dating this guy from my past. He was a sweet guy, but we were never in a relationship. We were FWB and actually really good friends. I cut out the sexual part of our relationship when I met my now husband and this friend stuck around and was still a good guy to me. In the dreams we are not having sex or doing anything of that nature. In fact we are mostly just holding hands and enjoying being next to one another. 
I am very happily married to the love of my life and have an 8, almost 9 month old, with him. I don't understand why I keep having dreams about this guy from my past.  What are your opinions/interpretations on this?
