Last night I dreamt about my son's father. We are not together and and have never lived together.?

In my dream he came "home" from work, but home was not my current home the set up was completely different. In the dream it seems as though we were living together. The odd thing about the dream other than us living together was he undressed and was in boxers the baggy kind - this is not the type of underwear he nomrally would wear. He was also rather affectionate with me. Sitting on the bed in his baggy boxers - just affectionate this was not a sex dream. Any insight would be helpful thanks.
