Meet Me in the Dreamland

Cara never met the guy in reality. She doesn't know his name. But in her dreams, they interact with each other. One day, she happened to bump the guy in his dream.
So he is real indeed! In flesh, he is more charming and he can be egnimatic..
Her dream was her only connection with him. She happens to predict his "future". She can see that he has special someone who is cheating from him with his best friend.
So she decided to catch the attention of 'the best friend', so that the man of her dreams will have a "happy ending" with his girlfriend.
Will she succeed? Or will she fall? To whom? To the man of her dreams? Or to the villain?
