The Whisperer in Darkness by H.P. Lovecraft

Do not ask me how long my unexpected lapse into slumber lasted, or how much of what ensued was sheer dream. If I tell you that I awaked at a certain time, and heard and saw certain things, you will merely answer that I did not wake then; and that everything was a dream until the moment when I rushed out of the house, stumbled to the shed where I had seen the old Ford, and seized that ancient vehicle for a mad, aimless race over the haunted hills which at last landed me-after hours of jolting and winding through forest-threatened labyrinths-in a village which turned out to be Townshend.

You will also, of course, discount everything else in my report; and declare that all the pictures, record-sounds, cylinder-and-machine sounds, and kindred evidences were bits of pure deception practiced on me by the missing Henry Akeley. You will even hint that he conspired with other eccentrics to carry out a silly and elaborate hoax-that he had the express shipment removed at Keene, and that he had Noyes make that terrifying wax record. It is odd, though, that Noyes has not even yet been identified; that he was unknown at any of the villages near Akeley's place, though he must have been frequently in the region. I wish I had stopped to memorise the licence-number of his car-or perhaps it is better after all that I did not. For I, despite all you can say, and despite all I sometimes try to say to myself, know that loathsome outside influences must be lurking there in the half-unknown hills-and that those influences have spies and emissaries in the world of men. To keep as far as possible from such influences and such emissaries is all that I ask of life in future.
