The Myth of a Mind

What am I?

Am I like a sunflower that
burst with happiness for a
short while then losses its
color and joy to the cold?
Or am I like a mighty bird
that soars through the skies
but soon must rest?

Am I like a closed book
that withholds many secrets
but is not open by anyone?
Or am I like a child who is
Unknowing of the world's evil
but becomes the world in the
blink of an eye.

Maybe I am like a good
dream that you only know
of in your sleep but when
you awake, that bit of
good is gone.

Or am I not?
