I have always believed that dreams manifest themselves in your brain, based on things that you think about during the week, or things that you hold close to your heart, or even things that you fear. Dream books will tell you what such and such an item means, but your brain has referenced that object to your specific emotions. And sometimes you dream just for the hell of it.
Disclaimer: I am not a professional dream interpreter. It seems there are some strong emotions present. It seems that you are hurt that you 'lost' her, whatever way that may have been.
This strong emotion manifest itself into the 'boyfriend/girlfriend' pair, giving your brain a reason for you to feel even more hurt. The ring and necklace elements give your brain a reason to feel embarassed, and her rational for not embarassing herself, is yet another reason for you to feel hurt. Her being really thin and dolled up could be your brain giving reasons to not want her any more.
First, let me say, I am not a dream expert and have no idea what your dream symbolizes. But, your dream would make a great romance novel. I was riveted to the detail and complexities of the characters.
Maybe, it's your sub-conscious telling you to use your life experiences in your new career as a writer. You've got a great start just add a few more words, a little more detail and some background information and it's a winner. Good Luck :).
Trust your heart to tell you what to do. The pain we experience and perceive is truly a barometer of the Destruction we perceive being done. We often categorize experiences as small or large, depending on the loss we think we experienced.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
