I've experienced dreams like that, I tell you, its not real as the way you hope it is. Dreaming is a beautiful gift, an opportunity to change real life events or persons to something better (or worse:P), but its all happening in your head, I believe. BUT those dreams and the feelings what came along with them are the part of your memory now! you can keep them (that is my suggestion) or of course you can face the truth by speaking with her, but don't build on a dream anything
