This song is about a guy who looked into the abyss and came back a changed man. Thus the lyrics "I have seen what the darkness does (Say goodbye to who I was)".
The whole idea seems to be that there are some experiences in life that change you so completely that your old personality sort of fades away to be replaced by something different and still your own. It's a really beautiful song and presumably reminds other people in addition to me that there are some things that really do "matter" for lack of a better word.
