Why am - I?

I had a dream where life was a thought
In this dream I lived, and i did that whitch i do
When i opened my eyes every thing was odd
Water, tasted new and the air smelt thin

How odd that I live, and yet stop and think of all of it as new
when I began to walk I find it so difficult to move with out thinking - why?
How can I live if the thought of me living was a spin chilling reality
When I lay I can feel the world spin
Some times I forget to beath
And when I hear my hart beat
I almost feel annoyed at the repatition
Over and over the same beat
Duh-da Duh-da
I think to much
I see more than is really there
How strange? To be.
Most of the time when I think
I make my self sick, I will tell you now
It hurts me to think.

I hold my breath and bite my thoumb
And try to think of a other thought
But its like my mind is drawn to it
Like rain to a hopfull day
I have hopes and dreams
But they feel like jokes
Why to I think? Why do I.... Why?
And why am - I?
