by Bram Stoker (excerpt)

I was not alone. The room was the same, unchanged in any way since I came into it; I could see along the floor, in the brilliant moonlight, my own footsteps marked where I had disturbed the long accumulation of dust. In the moonlight opposite me were three young women, ladies by their dress and manner. I thought at the time that I must be dreaming when I saw them, for, though the moonlight was behind them, they threw no shadow on the floor.
