WHY DO I KEEP DREAMING ABOUT BOYS FROM THE PAST

This dream was about the boy from this summer
  1. I went to dye my hair and he got pretty upset
    I'm planning on dying my hair next week so maybe that's why it happened in my dream?
  2. He never liked the idea of me dying my hair
    Lol
  3. He told me he wanted to keep in contact in the dream
    Like for a while?
  4. ^ that was funny because we haven't talked since August
    Lol, again
  5. So are we still on a break?
    ???
