a lot of people believe that our dreams are our subconscious trying to sort through our daily lives. it would seem that you still have a lot of unresolved issues with your friend. the dreams seem to decrease after the talk but there is still a lot left unsaid. perhaps if you wrote a letter, not one you send, just one that you write everything you ever wanted to say about this relationship. where you dont have to be careful about language or hurt feelings or embarrassment and get out everything that is bothering or hurting you and when you are ready to let go, burn it. maybe then you can have some peace. take care
