Art, imitating life the way life is if we doubt or disbelieve everything we know about the world?

Listening to Simon and Garfunkel's album "Parsley, Sage, Rosemary and Thyme" and going a little crazy with Kant I hear the lyrics:

"Through the corridors of sleep
Past the shadows, dark and deep
My mind dances and leaps in confusion
I don't know what is real
I can't touch what I feel
And I hide behind the sheild of my illusion"

These lyrics, from the opening of the song "Flowers Never Bend with the Rainfall," sure sound like Descartes with Cartesian doubt and the Veil of Ideas and the general state of confusion he leads himself and his reader into.

So, art is imitating the way life is if we can know nothing about life and if we doubt or disbelieve everything about the world we know?

It is a good song. I'm going a little crazy here.
