This made for very interesting reading. A well crafted horror story is an area of immense interest to me. And pondering on what made it truly effective as a horror story is at the heart of the interest. I have often wondered on this, from a literary point of view, but also from a psychological perspective also. And yes, the Unknown plays such a vital role there. Why can't we just be with what is and feel comfortable with our unknowingness? What is there that we are afraid to look at? And from there we have the seed of the horror, as the author uses words to play on what already exists within our psyche.
