I found this site Skeptical Analysis of the Paranormal Society...it is worth going through, it has attempted to explain the origin of paranormal stories in a bit alternate way.
Here's what the main writer had to say about the origin of belief in ghosts:
The History of Ghost Stories
Often, when reading accounts of ghosts in various places (like the "Haunted Red Lobster Restaurant" I've mentioned so many times before) I have wondered why, originally, the idea of ghosts first fascinated man. To me, the best evidence for the existence of ghosts was the way they permeated every culture. They crept across the globe. If they didn't exist, then why would so many vastly different cultures believe in them?
The answer may be found in the content of ghost stories. According to About.com's history of ghost stories, the majority are concerned with unfinished business ? most notably, their own proper burial. Virgil's "Aeneid" and Homer's "Iliad" both contain ghosts concerned with their burials. These are two of the earliest examples of ghosts, and even then, their burial was the concern.
It struck me that these ghost stories may function in the same way that urban legends do. Snopes.com says that urban legends "reflect current societal concerns and fears as well as confirm the rightness of our views. It is through such stories that we attempt to make sense of our world, which at times can appear to be capricious and dangerous. As cautionary tales, urban legends warn us against engaging in risky behaviors by pointing out what has supposedly happened to others who did what we might be tempted try."
Urban Legends are complex warnings. Ghost stories may be the same.
According to the Wyoming Funeral Directors Association, funerary rituals date back to the very beginning of mankind. Supposedly, even Neanderthal buried their dead.
Fear was often a driving force in these early burial rituals. Many cultures considered dead bodies to be "unclean" or "polluted". This was an extremely important belief and, in the same way urban legends do, it helped reinforce a belief that would assure the survival of the culture.
The Australian Museum Online has a section devoted to the changes that occur during human decomposition. These changes include an inability to fight off bacteria. Corpses become playgrounds for bacteria, parasites, and larvae. Keeping a corpse around would spread disease, attract predators, and either seriously disable the tribe or wipe it out.
Burial is important.
So when we take a historical view, looking back at early cultures and their ghost stories, concerned with burial, it's possible to conclude that they were designed to reinforce behavior. The best way of getting the word out on something was to create a story everyone would hear and be interested in, to ensure that the dead were buried, and the tribe could continue. Germ theory didn't exist then (it was developed by Louis Pasteur in the 1850's). It wasn't as though the tribe could sit down and say, "Hey, we've gotta bury this guy, because otherwise we are going to catch something."
This is what is added further in response to a question:
The Egyptians also had burial rituals and personified inanimate objects, but I haven't read any Egyptian ghost stories as yet. I will say that before we had scientific understanding, we gave natural phenomena credit for sentience (the weather, for example.)
Why? Because without a sentient explanation, you are seeing something happen without a reason. There must be a reason, and it is the human way to search for it.
How does this relate to ghosts? Well, if what you know is that hanging about dead bodies will make you sick, and you believe completely it has to do with a curse or magic, then there must be someone controlling it.
Curses don't get cast by themselves. The story can never be told unless there is a ghost to tell it, because curses don't have mouths. The dead do. So one must be resurrected to tell this story.
Why they all have the same rough appearance (white, gauzy, cold) is fairly easy to understand in these terms as well. Dead bodies are cold. They quickly become pale because of the lack of blood circulation. It gets grosser if we keep continuing on this path, but you get the idea. The physical appearance of a ghost would be much like the appearance of a recently dead person.
I hope that clarifies a little. As I said, there is no way to prove whether or not this is true as there simply weren't written records to indicate the mindset of man in the stage we're looking for. But the similarity of the reason for the ghosts appearance combined with the physical characteristics is interesting. I'll be doing some more research on this front
Sorry for the enormous post. Although I dont agree or diasagree with any view point at the moment, this is a different angle to look at the ghost phenomenon, and the site is worth a try.
