Fear is one of the most primal emotions we posses, one that we first encounter during childhood nightmares. The terrifying moments we experience in our unconscious is what prepares us to deal with stressful and horrifying moments in later life quickly.
The point at which you wake up, usually the moment of death in a nightmare, leaves a lasting image in the mind. Much like the Victorian belief that you could extract an image of the last thing a person saw before they died from the retina of their eye.
It is these images from my nightmares that I remember from when I was a child that I reproduce, to bring them into the cold light of day to examine, and show that these archetypal images contain no more fear.
