Either the world's getting more haunted or people are more bored and delusional than ever.

According to a new survey, 25% of people say they've seen a GHOST.

In a similar survey in the 1950s, only 7% of people said they'd ever had an encounter with a ghost.  That was up to 14% in the 1990s and 19% in 2003.

A professor at the University of Hertfordshire in England thinks the rise to 25% might be because of more paranormal and supernatural themes in TV shows and movies . . . more ghost stories make more people believe in ghosts.
