Kissing my ex-girlfriend

In one night, I dreamt of kissing my ex-girlfriend in two different scenarios. In one dream I hadn't seen her for a while and all of a sudden I visted her home, met her parents and we were kissing.

The second one, I dreamt that I came to her rescue and kissed her passionately. Then I said something like this "Your prince charming has come for the princess" we kissed again....

I don't know what this meant. Please analyze this dream.
Thanks.
