What Does It Mean, I Really Traveled Through Time?

What does it mean, in a dream, I really traveled back to my junior high school days? My name is He Yiwei, an ordinary college student. I missed my girl in junior high. I thought I had given up, but who knew, a note in the mysterious wishing box would make me think a lot. "Let me make your wish come true." You just threw the note in, right? Then let me make your wish come true!
