I think it might mean that you are missing your friend. I know that's a stupidly obvious thing to say, but we choose people as friend because we connect with them on a certain level, we have an understanding with friends and they (we hope) understand us in ways that most other people do not. I think your friend appearing in your dreams now represents a need for advice from a personality that your subconscious normally associates with your old friend.
I mean that your dreaming mind is using your friend’s image because it connects the way you feel about her with the type of advice and guidance it thinks you might need now.
Or it could be more straight forward than that, like you do actually miss her and your dreams are making up for that by having her be in your dreams so you can get an idea how you might feel if you did go and talk to her in waking life.
What do you think?
