How can I explain to you who are unafraid the meaning of fear?

It starts with the elusive beast
Who lives around the corner of childhood
It bursts into roaches that fly while I bathe
And softly it steps through the shattered glass.
Through window cracks it howls and rustles
In slow footsteps that tread on my dreams
And then it embraces me like a hot blanket
Of madness.

How can I explain to your reasoned mind the flaws of my senses?

My sense of reason is a two-headed child
One head is the calm of courage and thought
The other is the maniac of fear
They were born in the womb of my rapid imagination,
And this poetry I claim is their brother again.
And yet it seems I am born of them all,
Made complete somehow by their ruthless existence
Of weakness.
