This is just me kindof thinking out side the box(:
I think this soing is about a boy meeting a girl, ok? Well turns out he really like this girl but they're only going to meet once and he basicly saying hes trying to find this girl but its not going to happen. The girl he meets is just like one he might of had in his dream. But since he never found her. She just floating around in his dreams. Hes sky high.
