@darya: Have you ever seen "girl interrupted?"
there's a lot of movies, books, songs, about women with qualities that are not "socially acceptable" but "totally hot". Also, those women are usually like that not because they want to, but because they are. Shyness makes you less approachable and thus more attractive, Quietness makes you mysterious, Being unpredictable IS one of the universal signifiers of dominance and self esteem (even if you don't feel that yourself).
