I had a dream about my this girl i like?

so i went camping over the 3 day weekend with my family and i had 2 dreams about this girl ive had a crush on since end of my ninth grade year (now the end of 11th grade year). Well in the first dream we were talking on the bleachers and her friend came and got her attention away from me some how i ended up grabing both of her hands and i had her pinned down and i just went in for the kiss and when we were face to face she said my name followed by a pause and then she said how did u know? i kissed her and i woke up(bummer i know wud have been first kiss for both of us) the next night i had another dream and we were totally ignoring each other we were in a classroom and i left the room and we made eye contact but that was about it didnt see her for the rest of dream. i know dreams are supposed to prepare u for real life situations in wich u might not know how to react or w/e. but why wud i dream this if i know she dont like me cuz i already asked her out and she said no. why do these things still cross my mind is it cuz i still talk to her?
