While opinions vary on this, it can be said that according to what one might call "mainstream scientists" or the "scientific establishment", there are no "real" ghosts.
Therefore we could say that the percent of real ghosts is zero.
I am aware that some will not agree with this. They may have volumes to post on how Established Science, usually for reasons of ignorance, blindness or even dark conspiracies, hides the proof of ghosts - or aliens, free and unlimited power sources, cancer cures, etc.
Let us all please remember that the scientific establishment, for all it's flaws - and it does have them - has provided us all (even the poor) with a standard of living that leaves the grandeur of ancient kings in the dust.
In the absence of real and verifiable proof, it is not credible to believe in ghosts.
Ghosts are real if you believe in them. Monsters are not real.
Ghosts are not real, so there is no place they hide.
No Ghosts with clothes on aren't real either.
Nobody really knows that ghosts exist in the first place. So to speculate whether we appear to ghosts as ghosts is jumping the gun. So far there is no proof at all that ghosts are real. Until there is, it's perfectly rational to conclude they are not real. I think they are not real! WRONG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! GHOSTS R REAL you are apsilutly right ghost are very real there are ghost everywhere!
Members of ClubPenguin can dress up as ghosts, but no there are no such thing as real ghosts on club penguin
Yes ghosts are real because i have 3 ghosts in my house.
No spells get rid of ghost. Ghosts are not real and spells are not real.
None whatsoever. Ghosts are not real.
No as ghosts are not real.
ghosts aren't real
There is no real proof so only if you strongly belive there are ghosts, there might be ghosts.
There are ghosts only in our minds.
