She hasn't noticed me and I question whether I should introduce myself. What would I say though? My name is Kai and I've been dreaming about you for years upon years? No. Or, My name is Kai and may I just say that you bear a striking resemblance to my dead fiancé? That would surely not scare the girl off. Or I could say: Hey, I just met you and this is crazy, but here's my number. So call me, maybe? I ponder this but decide against it.
