Twenty Years' Experience as a Ghost Hunter

I mentioned in one of my former works that I believe many of the figures we pass by in the streets are not men and women like ourselves, but phantasms-phantasms of the living, that is to say, spirit projections of people consciously or unconsciously thinking of being where we see them-phantasms of the dead, and impersonating neutrarians. Mingling with the crowds in the parks and gliding in and out the trees, I have often seen people with the pallor of corpses; I have followed them, and they have unaccountably vanished. I believe Hyde Park, particularly the northern side, to be as full of ghosts as any spot in London, and I have heard many strange tales from the outcasts, the tattered and torn brigade, who have slept all night under its trees and bushes.
