A Descent into Egypt by Algernon Blackwood

I made a violent effort, then, at self-assertion an effort to focus my mind upon the present. And, searching for Moleson and George Isley, its nearest details, I was aware that I could not find them. The familiar figures of my two companions were not discoverable.

I saw it as plainly as I also saw that ludicrous, wee piano for a moment. But the moment remained; the Eternity of Egypt stayed. For that lonely and terrific pair had stooped their shoulders and bowed their awful heads. They were in the room. They imaged forth the power of the everlasting Past through the little structures of two human worshippers. Room, walls, and ceiling fled away. Sand and the open sky replaced them.
