Context: I walked down the basement stairs much as I did any other normal day . If I were n't covered in blood it would have almost appeared like I was going to check the dryer . There was no hesitation , no fear ; just blank , empty locomotion . An automaton moving toward the open window above the dryer , somewhere inside hoping that one of those things I had seen earlier would come up behind me and end it before any of this had the chance to sink in .
