All houses wherein men have lived and died Are haunted houses. Through the open doors The harmless phantoms on their errands glide, With feet that make no sound upon the floors.
We meet them at the door-way, on the stair, Along the passages they come and go, Impalpable impressions on the air, A sense of something moving to and fro.
There are more guests at table than the hosts Invited; the illuminated hall Is thronged with quiet, inoffensive ghosts, As silent as the pictures on the wall.
The stranger at my fireside cannot see The forms I see, nor hear the sounds I hear; He but perceives what is; while unto me All that has been is visible and clear. […]
So from the world of spirits there descends A bridge of light, connecting it with this, O’er whose unsteady floor, that sways and bends, Wander our thoughts above the dark abyss.
Henry Wadsworth Longfellow
