There are many explanations for dreams. It is possible that there are two parallel dimensions in which holds the key. It is possible that in this other dimension you make the exact opposite decisions as you yould make in this life. thus each time a path is chosen, a line so to say is born and when these paths/lines cross it seems like the event in your life has happened before. This can have a direct relation with your dream, or can relate to what your dream is about.....
