patriot, all others:
I think that we should bring the word 'Ghost' into the 21th Century, England and Shakespere used two words to signify a disembodied spirit, 'Ghost' and 'Sprite'.That is why the King James Translator have the Disciples seeing Jesus walking on the water and they said it was a Ghost and they have that Jesus giving up the Ghost. The validity of spirits walking the Earth aside we should use the word spirit, though I don't think the world will ever change terminology.
Though I don't believe that a spirit linger on the Earth, I wouldn't wish to spend the night in a purported place of so-called hauntings, that is just human nature.
In Louisiana, we have our places of hauntings, as it is believed, such as in Baton Rouge, it has been reported that Confederate Soldiers have been seen walking a street.
I believe that a tide of interest in spirits has arose due to paranormal shows, it is very sad to see this in the natural man (sinner) and Christians.
[i welcome moderation if I give too much "glory" (not meaningly) to the paranormal.)
