I really am not clear on the meaning either.
I think it could mean diff. things.
I think the main idea of the song is that the singer feels like someone he used to know well has changed.They went away & they've com back & he feels like they're a totally different person now.
Also get the vibe that hes haunted by something. He doesnt want to turn out a certain way or make the same mistakes he's seen this person make.
