In your dream, your friend represents an aspect of your concious thinking. Look at her personality as you know it. The traits you see in her are the same traits within you, that the dream is addressing. So, not only do you miss her, but, there is a part of you, that you feel like you haven't seen for awhile. The kiss indicates that you are 'warm' to this part of your personality. Look over your life and see where you may have gorten caught up in life's activities only to realize that there hasn't been time for you. Perhaps a new class, kids, a job...it's easy to neglect or 'subdue' parts of yourself in favor of dealing with other stuff. Hope this helps. God bless.
