What I find curious are "ghosts" who are regional, and ethnically so. You don't see mononoke in the English dwellings, or Grey Ladies in Africa, or US Civil war soldiers in South America. Nope, the wailing betrayed hair-in-the-face ghost girl stays in Asia, Grey Lady sits around in her house, and US Civil War Soldiers haunt, well, the US. What's with all the restrictions? With all the travel that's gone on in the world, can we have some ghosts are of Japanese descent and suffered in the American relocation camps? Can we get an American soldier who died in Vietnam? Or a Canadian who died in France? (Oh, well, I guess the last one is the same thing...)
You have just bumped into the RULES. These cover various aspects of the paranormal and there are sub-sets that deal with each specific area. The rule that you are referring to is the nationality/ethnicity rule. In the US and UK ghosts tend to reflect rather victorian dictates. Other rules reflect the presence of believer or language. Ian gave a good precis of an Uber rule:
... It is certainly possible that some ghosts have an external origin, but are not an integral part of this empirical reality so to speak ie are not physical.
We have, you will note, sort of assumed their existance and then jumped, immediately, into the RULES. The key to understanding paranormal doublespeak is the use of the word "some". Also the use of words like "external" and "empirical". The set up is that we have, in a few words set up at least four kinds of ghosts: external and (presumably) internal and for each of these types physical and not physical. Bear in mind the use of the word "external", that could be license for anything.
Just consider ghosts seen during NDE's (being of light, relatives, friends).
Again you are being drawn in. We have established that ghosts exist and now, without pause, talk of a certain type. Is it true? Who knows, who cares.

Clearly they are not physical but that certainly doesn't necessitate they are a hallucination!
Golly, no!. Bold statements are key, as you are seeing. We have established their existance by fiat and now their "existance" argues against hallucination. We have (and necessarily) lost complete sight of the basic question.
And consider death-bed apparitions. The dying person can see the ghosts, but not normally the people at their bedside.
We have here lost all semblence of reasoned discussion. What the poor dieing sod can only be experiencing are "apparitions" which immediately become "ghosts". The use of the word "normally" is to provide the illusion of a grounding in reality. Again, sometimes they see 'em, sometimes they don't.
On the other hand reports say that sometimes the people at their bedside can see what the dying person is seeing. But I doubt whether the image could be captured on a camera.
So now we inject a real spinner. They are not physical (sometimes? all the time? who knows) yet they deplete visual pigments, a physical process. So they must be physical, right? No. You forget the rules. Remember this statement?
... It is certainly possible that some ghosts have an external origin, but are not an integral part of this empirical reality so to speak ie are not physical.
This is the get out of jail free card. "External origin" could mean anything at all. Often this is where we see some invokation of QM or somesuch.
Just remember Rule #1: There are no rules.
