What does this mean? 2 Questions?

Ok so last semester i was best friends with this girl. we would hang out all the time and we always had the best time together. Also, i liked her, but i didnt think she'd like me back because shes really picky about who she dates, and if a friend likes her and she doesnt like them back, she'll leave them alone until they get over it, which means total ignoring, and i didnt want that. Well i started hanging around with this other girl, and i started feeling a little bit for her, so i had to choose, and so i figured it was better to stay friends with the first girl and not risk our friendship, and just chase after the second girl, who i never got to date. Me and the second girl are friends though, which the first girl didnt like, since i always got hurt by the second girl. I asked the first girl for advice and she gave me some, but she didnt want me to stay friends with her, but i did anyway. Now, the first girl wont even look at me. She's been ignoring me for over a month. Why is she doing this? Is it because she likes me?

Second question (this is for people who believe in meanings behind dreams): I've been trying to fix things with the first girl for a while, but she would never give me a chance, so eventually i just gave up trying. For the past 2 days, i've been dreaming about her. In the first one, i cant remember much, but either she went to me, or i went to her and she actually let me talk to her, and we made up and stayed friends. In the second one last night, i had a dream that i went to her and tried to fix things, and she let me, and one thing led to another and we ended up dating... Does these two dreams mean anything? Or am i just dreaming about what i wanted and what i missed out?
