The weathercocks on spires and housetops were mysterious with hints of stormy wind, and pointed, like so many ghostly fingers, out to dangerous seas, where fragments of great wrecks were drifting, perhaps, and helpless men were rocked upon them into a sleep as deep as the unfathomable waters. – Charles Dickens, Dealings with the Firm of Dombey and Son

A house is never still in darkness to those who listen intently; there is a whispering in distant chambers, an unearthly hand presses the snib of the window, the latch rises. Ghosts were created when the first man woke in the night. – J.M. Barrie, The Little Minister, 1891
