Sometimes I have dreams that help me prepare for what is to come. I like to think of them coming from my higher self.
You had mentioned your family background, having been through a lot of changes lately and that you are about to be married. Having had a similar family experience, you may have spent most of the time with them or with people reacting and defending as I have. I think the dream was a way for you to question yourself about your own desires and initiate a situation in which you answered your own question, which may not have been conscious to you.
Very cool.
