Why we fear ghosts

People fear ghosts for two reasons: one, they symbolize death, something all humans are hardwired to fear.  Two, they represent the unknown, and, as lovecraft once said, the oldest and strongest fear is the fear of the unknown. 

Thus, humans fear, usually, ghosts.  It's not so much that they exist, but the things they represent.

Summum Nec Metuam Diem Nec Optima

I think that about sums it up really, I wouldn't say there was much more to add - fear of the supernatural is really fear of the unknown

hey I used to think I was a Spartan too...during the time of Brasidas though. But a friend of mine....a very wise man....told me that I was just sensitive to time itself....that I was in tune with the ebbs and flows. That's why some things totally unrelated to one another...at least when I first get involved with it.....appeal to me. You can imagine my surpise when I find a connection.

Oh...fellow Spartans....doesn't it just tick you off to no ends that the modern writers can't tell the difference between or cheese game at the alter of Artemis to the brutal post Roman conquest monstrosity that no real Spartan would have allowed?
