Interesting, your sounds symbolic. I will try to tell your dream again you tell me where I have it wrong.
Sounds like you are a true romantic! Interests or possible dates have not been appealing to you. Maybe lately, there are people interested in you that you are not attracted to or even repulsed by. Your brother is extremely protective of you, even if he may be one of those siblings who behave as though they don't care about your dating life. No one is probably good enough for you in his book. "No frog is good enough for the kisses of my sister" attitude. OK I'm going a bit far but you get the point.
If you're married-disregard everything I said. What you said is true-you have some weird dreams
