Problems...
A) She doesn't remember her dreams
B) I have dreams about people all the time. But I don't go to them and say "HI I HAD A DREAM WITH YOU." You can't really bring it up... "Hi have you had a dream about me yet?," and I highly doubt she will.
C) Just talk to her...
D) "Shared dreams" are not what I would call "possible."
E) Why would she like you more if you were in her dream? That really wouldn't make much of a difference if she isn't interested in you in the first place.
