I find this song to describe how Cloud felt as he dreams about Aeris for the last time and her subsequent death:

I have you in my dreams at night
you were holding my hands
then I awake and you're not mine
now it's time to rise

I want to turn cold ice in my soul
got to freeze this yearning inside

When you're inflicted by
the passion of love
desire and yearning the
deeper they burn
you were...
now it's too late
you were...

Now you're gone
It's too late
I was wrong
It's my fate

"I think of you and I see me
I'm the one I thought I've never be
I feel dirty - no purity
desire and yearning in you heart
no mercy for you no mercy for me."
