I agree with Browns0286 as well but I also think it could be some sort of reflection of the self..as if you were remembering everything that happened before the glass of what you thought life was shattered, when you still had light (hope) in your eyes, when everyone was still hopeful and everything was so much easier before.

While pondering you ask yourself if you even saw it all coming, if you even saw the windows being closed and the doors being shut by the people that you loved, who moved forward without you.

What was it like? What did they look like? And you think, you once knew them so well, as if like children, when you were so optimistic about everything, then when everything ends you find that you now know nothing about them or even yourself at all.

People call you out on it, but you keep denying that you still care about them or that you're alright. But it's all just dead, lifeless hearts walking around you. Yours may be one as well.

ghosts of your pasts maybe as well?

Wow - this is a really good interpretation. It hadn't occurred to me that she could also be talking about her young selves. That's arguably an even more sad meaning for the song.
