The choice of belief towards ghosts or towards mental people, should easily be put in favour of the mental people camp, as there are millions of proven and listed sightings of mental people. As mental people have been proven to exist tens of millions of times over, and with billions in global currency already spent on the mental health sector with nut houses being built all over the world, and indeed argued that most prisons are infact an extension of the nut house system, it cannot be argued that nutters don't exist. It can also be argued that nutters often claim to see ghosts. So nutters that have claimed to see ghosts, have been proven to exist in the millions. But it does not mean therefore, that millions of nutters who see ghosts, means that the ghosts that they see are real. So mental people exist, and ghosts don't exist, only mental people that see ghosts.
