Many of the recent ghost stories are created and puffed up by those who wish to cash in, or who just like to watch other people run around like lunatics. It makes for some good scripts, though. In Lord Of the Rings, rings of power sap the real-ness out of rulers and make them into slave wraiths. It's generally thought that Shakespeare didn't really believe in ghosts, but that didn't stop him from making a great turn of plot with the ghost of Hamlet's father. The same is true of those Hollywood script writers (crypt writers??) and TV moguls who churn out ghost shows. In show biz, there are ghost riders in the sky on their way to ghost towns, and ghost whisperers that reach the haunting dead. When something supernatural like an apparition appears in a story, the dramatic tension shoots way up, as if to say 'here's an important moment where we learn what lies behind what's happening in the story'. (Unless, of course, they start sliming people.) Ghost stories can be rocket fuel for a young child's imagination about the world around them. I can recall one ghost tale which left me wondering all week long about whether the walls in a teacher's 'haunted house' held a dead body. In the process, I learned a lot about walls. But no spook has a ghost of a chance of collecting any royalties on the stories about them, nor does the ACLU sue over fomenting hatred of hobgoblins.
My own local Long Island 'ghost story' (really more of a paranormal/demon story, but those often cover the same ground) is the Amityville Horror house, where a modern-day real-life multiple murder took place. Reports about the presence of spirits by the next home owners led to bigger stories of ghost sightings, then news reports, then a novel, a movie, and a legend. This ghost story was spread for both fun and profit. Owners since then never liked their house's image as a haunted house, and have made it look very different. The truth is more than creepy enough. Murder of a whole family by a material human from that family is an evil that would horrify even the scariest specter.
Mark reports that when Jesus' disciples saw him walk on water, at first they thought he was a ghost (Greek phantasma). Then He talked to them and got into the boat with them, showing them He was materially for real. Check out Luke 24:36-39 : when Jesus came back from the dead, He was no ghost.
Sorry. You'll have to look elsewhere for ghost photos and art, or anything on Kerlian photography. This page is not haunted.
One last thing :
I ain't scared of no ghosts.
