For one moment I resisted the unreasonable terror, and made an attempt to explain, or at least analyze, a sensation so unwonted: the next, the loathing dread grew too strong. I turned and hurried across the damp floor, up the narrow stairs, and, opening the door, made my way as quickly as possible into the outside air. The dog was waiting for me in the little shed, and seemed delighted at seeing me again. I closed the door, ashamed of my senseless fright, but nevertheless I was thankful that I had found no trouble in getting out. I am not quite prepared to say, however, that these sudden and apparently unreasonable starts are independent of external causes.
