you dont understand

A phrase used when describe something in-descibable, used when you are telling a story or something and what you are trying to describe can not be defined by words or any other means.

And you don't seem to understand
A shame you seemed an honest man
And all the fears you hold so dear
Will turn to whisper in your ear
And you know what they say might hurt you
And you know that it means so much
And you don't even feel a thing
I am falling, I am fading,
I have lost it all
And you don't seem the lying kind
A shame that I can read your mind
And all the things that I read there
Candle-lit smile that we both share
And you know I don't mean to hurt you
But you know that it means so much
And you don't even feel a thing
I am falling, I am fading, I am drowning,
Help me to breathe
I am hurting, I have lost it all
I am losing
Help me to breathe
