It's definitely "I know this. I felt the same. I'm sinking by your side." Not "sleeping by your side."

What does he mean by "It's the wrong side of fear that kept me out."? its been bothering me ever since i listened to the whole cd cause it doesnt seem like a just ending to such a masterful album.

"Words of mine are trite and simple shame.
Still we find a place in everything.
It's just to break the silence that has been crushing me.
Half of me is dead, already gone.
Half is screaming everyone is wrong.
Finally asking now, will you just hear me out?

This was all my fault.
You brought me death, and it's everything I wanted.
It's the wrong side of fear that kept me out. "

I may be completely 100% off here, but it's interesting...could this be about a huge fear of commitment to someone he loved, and him, although knowing it was an awful thought to think but thinking it anyway because of his huge fear (possibly of commitment), thinking something along the lines of, "Damn, if this girl would just die or something I wouldn't have to keep feeling this way, so scared and nervous and worried about the future." - I don't know, I know nothing about this song yet (first time hearing it today), but the ending leads me to think about this.

It's about a girl who's dying/dead and he would give anything to have more time with. He blames himself for not treasuring every day with her.

Well if I remember right, Josh said in an interview that the emotions from all their albums come from what they are dealing with in their life at the time. (like As Your Voice Fades being about Toby's grandmother Now I'm not sure the exact intentions of the song, except that it was all built around "This Night Will Be Mine" being sung in Spanish.

Like the last poster said, I get a similar feeling when listening to the song.

Some of the lyrics are wrong. I have the cd! Came yesterday and I love it! <33 The correct lyrics fit, what people have been saying above about the meaning, better.
So here are the correct lyrics in booklet and I tried to set it out best, please change them thanks:

Time is running out,
As you die die die in this bed not making a sound.
It has all come crashing down,
To be here, and watch you breathe your last.
So helpless to stop you from slipping away so fast.

Oh God are you listening now?
As this cancer dances through her and then takes a bow.
It won't disappoint the crowd,
Whose words, are a curse,
As I hear them one by one.
Each pull, the string, and I come undone.

I know this, I failed to say (I'm sinking by your side)
You're worth this,
I wouldn't trade a day, to not have gone through this
So many days I've been blind
I want to stop and rewind
Kick off our shoes and dance, with the ghost of you.

Who could tease me and leave me begging for the abuse?
You're the only I knew,
That could tame me, and make me who I am.
But now it's all fading, and there's nothing left of all my plans.

I know this, I failed to say (I'm sinking by your side)
You're worth this,
I wouldn't trade a day, to not have gone through this
So many days I've been blind
I want to stop and rewind
Kick off our shoes and dance

Let's dance again
We'll turn up our sleeves
I know just where to begin
Dance, let's dance again
We could find ourselves before this happens

These words of mine are trite and so cliche,
And still they find their place in everything.
It's just to break the silence that has been crushing me.
Half of me is dead, already gone.
Half is screaming everyone is wrong.
Finally asking now will you,
Just hear me out?

This was all my fault.
You brought me death, and it's everything I wanted.
It's the wrong side of fear that kept me out.

Oops I missed a one out...above^^ 'You're the only one I knew'.
