Everything in dreams is indirect and real people will not represent themselves but rather their character qualities or your relationship with them. I think she represents your desparation to express yourself to her and your hope that she will feel the same way.

It's not herself that's highly emotional but the way you feel toward her. I'm not sure exactly how the dream works but you clearly have strong emotions for her that you want to get out and express.

My advice is go ahead and ask her out. If she says yes you will have GAINED something, and if she says no it will hurt you but you'll get over this enigma and get closure like you can't so far. I think this dream is just Nature encouraging you into pursuing.
