What is this dream about?

Ok I'm new to dream interpretations but i had a dream the other night that really stood out to me. Basically, it's like this, there was this girl i really liked and i had a crush on her but she turned me down in the end. The other night, I had this dream where I was with this completely different girl that I never met before. In this dream I got down on one knee and proposed to her, wanting to marry her. She got ecstatic and said yes. The next thing I looked around and I saw a crowd cheering us and congratulating us on our engagement. BUT in the crowd i saw the girl that rejected me and she got really upset and burst into tears. She then went up to me with tears down her face and went 'i thought you liked me!' and so on but i just told her off for rejecting me in the first place and that was it. What could this dream mean?

I think this dream is an emotional response to being rejected, basically this dream says "someday she will be sorry that she rejected me." In a sense it is a double wish fulfillment dream: one wish it is showing you as fulfilled is that someday you will find the one whom you will propose to and who will not only not reject you but will ecstatically say yes to you, but the second wish it is showing you a fulfillment of is that the girl who rejected you will be sorry that you did. It is just a wish fulfillment so not a prophetic dream, chances are that the girl will not be sorry, but you wish she were. If I were you I would concentrate more on the first wish than on the second: someday you likely will find the one whom you will want and who will want ou right back. Spending additional time wishing about the girl who rejected you is less likely to lead to a useful outcome in waking life, though it may result in satisfying dreams perhaps.
