Dreaming
During this third prostration before the dark idol, and after some years, new and monstrous phenomena began slowly to arise. For a time, these were neglected as accidents, or palliated by such remedies as I knew of. But, when I could no longer conceal from myself that these dreadful symptoms were moving forward forever, by a pace steadily, solemnly, and equably increasing, I endeavoured, with some feeling of panic, for a third time to retrace my steps. But I had not reversed my motions for many weeks before I became profoundly aware that this was impossible. Or, in the imagery of my dreams, which translated everything into their own language, I saw, through vast avenues of gloom, those towering gates of ingress which hitherto had always seemed to stand open now at last barred against my retreat, and hung with funeral crape.
As applicable to this tremendous situation (the situation of one escaping by some refluent current from the maelstrom roaring for him in the distance, who finds suddenly that this current is but an eddy wheeling round upon the same maelstrom), I have since remembered a striking incident in a modern novel.
