What are these reoccuring dreams telling me?

I believe in the subconscious mind sending messages through our dreams but I am not sure what my mind is trying to tell me!

I am recently married in a very loving, secure, healthy and happy relationship. We have been together for over 5 years and are very solid.

I come from a tainted past (as everyone does) with a lot of familial dysfunction, emotional neglect, and lost loves.
Two weeks ago I ran into my first love whom I have not seen in over 5 years. Our relationship and ending of was a significant source of pain and trial in my adolescent years. It launched me into years of therapy with all the other family/growth struggles I was going through at the time.

I spoke with the ex-boyfriend for about 5 minutes (my husband was there the whole time). At first I was fine, but after a few minutes I had this odd feeling in the pit of my stomach. It was almost as though my stomach was shaking. I began to get very nervous and I calmly/casually ended the conversation with a “it was nice to see you…take care, etc.” This was an interaction I had always wondered how it was pan out…it went well!

Since this reaquainting, I have had reoccuring dreams of the ex-boyfriend. Rehashing old issues, calling him and trying to find closure. Sometimes in my dreams it starts out that it is my husband who I am fighting with and then it turns into the ex-boyfriend.

I am wondering what my brain is trying to tell me. Clearly, I am not over some of the pain…but I am trying to find out how I can help myself deal with this.
