If it's really bothering you then you should talk about it. Maybe it pushed a button, as in your parents laughed at you and you never processed that , something along those lines . Or... If you forget about it in the next day or so it might be no big deal. If you were talking about a dream I think those kinds of things can be silly, Hell, even the worst tragedies can and are made funny. (Check out comedian Tig Novaro if you don't believe me.). Sounds like she got serious when she realized whatever it is really bothers you, and that's what counts the most to me
