Suggestions:
1. A (continuing) greater interest and awareness.
2. The media feeds on - and creates more - interest in ghosts, ghost hunting, mysticism, angels, witchcraft, vampires, etc. Its all about the Almighty $
3. In the post-modern, post-Christian age, people are increasingly hungry for some sense of "spiritual" experience.
4. The plethora of "ghost hunter" TV shows leads more people to actively seek out paranormal or supernatural experiences - and when you're actively seeking, you're more likely to "experience" one.
Cognitively speaking, there may be other reasons. Since the early 1990s psychologists have carried out a huge amount of research into the cognitive processes underlying belief in the supernatural. One thing that they discovered was that those who believed tended to have a weaker understanding of syllogistic reasoning (basically, evaluating whether a conclusion necessarily follows from two premises). Their concept of randomness is also distorted, leading them to see "meaning" where there is none, and they are more suggestible. There is also growing evidence that "believers" tend to be more prone to false memories.
That
might be translated by some as a long-winded way of saying more and more gullible people have access to the internet year after year. But I specifically did
not say that.
