Hi and welcome to Dream Views.

I suck at interpretation too. But that is an intersting dream. Perhaps it was a sign that you have reached a new level of friendship with her?

In the end the only person who can truly interpret your dreams is you. Most likely your future sister in law is merely a symbol for something else. What? I don't know. Only you could answer that.

Any other questions feel free to pm me or the other dream guides (those of us with green stars). I can help you with just about anything BUT interpretation.
