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.
Excerpt from: Haunted Houses, by Henry Wadsworth Longfellow, 1858
