Dream notes and associations

When Penny and I first met, I was living in Canberra, and Penny was living in Sydney. Early in the relationship, Penny told me about her best friend, Margaret. They had first met as flat-mates in Sydney, and the friendship had grown from there. They had flatted together for a number of years in a number of different addresses. Then Margaret got a job at the ANG in Canberra and moved there to live. The friendship continued for awhile but they lost track of each other. Penny told me that she would like to reconnect with Margaret. What Penny didn't know was that, in the meantime, Margaret had married into a family that were close personal friends of my family. 4 days after this conversation I discovered this connection and the following Saturday (Christmas Day, a very surprised Penny had a reunion with her long lost friend. I actually didn't know, nor had I met Margaret, up and to the point, but my parents knew her. My mother knew her very well, in spite of the age difference.
The male boyfriend, although I knew him in the dream, outside of the dream, I do not recognise him.
I recently realised that all our friends are, primarily, Penny's friends. My only 2 friends are the other Penny, who now lives down the South Coast, near the Victorian border, and Richard, my former dream therapist, who lives up on the Sunshine coast. Richard was one of the friends meeting us at the park.
