What does it mean when you have a dream about a friend and she is holding you and acting like as if you were in a relationship?

It only means that you, the dreamer, long to be in a loving relationship. You might be starting to care more about your friend, but it is also possible that in this dream, your friend merely represents attractive females in general. The dream does NOT provide any insight into your friend's thoughts or feelings, only insight into your own emotions.
