Old Crush

I had another dream of my high school crush, someone who rejected me in the past back when i was in high school. In my dream im riding next to her in her car, riding alongside thinking how her rejection was in the past and i didnt really have feelings for her anymore. She was very attentive in the dream, more invested in making me feel better and keeping the conversation flowing. Anyway, i get off her car and she starts giving me books, i ignore the 1st and reply i've read it before, the 2nd on i say "nah this is too technical for me to read", and the 3rd i take approvingly and see that its about astrology and i take it with me. She drives off and the dream ends. In real life im not as cool headed as i was in that dream, i get nervous around her and i feel awkward when she's around me. Any thoughts into what this might mean?
