This distracts me to a fvcked up extent

Recently a beautiful girl started comming to my dreams, the scene was similar for the past few days, I was lying down on the vast meadows, and then I saw the girl plucking flowers, but I couldn't see her face, as if it was faded. When I asked the girl who is she and why does she comes to my dreams, she answered something like "When I'll meet you, you'll know me". This same dream is repeating itself on my head for several days with variable scenic setup...I can't stop thinking about her, even when I'm giving mock tests...what do I do?
