Good article in Slate on the neurology of Out of Body Experiences, and Near Death Experiences:
But the fundamental reason that hallucinations — whatever their cause or modality — seem so real is that they deploy the very same systems in the brain that actual perceptions do. When one hallucinates voices, the auditory pathways are activated; when one hallucinates a face, the fusiform face area, normally used to perceive and identify faces in the environment, is stimulated.
The tendency to spiritual feeling and religious belief lies deep in human nature and seems to have its own neurological basis, though it may be very strong in some people and less developed in others. For those who are religiously inclined, an NDE may seem to offer “proof of heaven,” as Eben Alexander puts it.
Well worth a read. The bus conductor who had seizures of bliss, which respectively took him from heaven to atheism over a few years, suggests neurological factors and personal responses to experience are key.
Rather than a ghost behind your eyes waiting to escape.
Photo taken from blog here. I quite like the “scientists must you ruin everything!” Think Dawkins answered that one best:
“We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Sahara. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively outnumbers the set of actual people. In the teeth of these stupefying odds it is you and I, in our ordinariness, that are here.
Here is another respect in which we are lucky. The universe is older than 100 million centuries. Within a comparable time the sun will swell to a red giant and engulf the earth. Every century of hundreds of millions has been in its time, or will be when its time comes, ‘the present century.’ The present moves from the past to the future, like a tiny spotlight, inching its way along a gigantic ruler of time. Everything behind the spotlight is in darkness, the darkness of the dead past. Everything ahead of the spotlight is in the darkness of the unknown future. The odds of your century’s being the one in the spotlight are the same as the odds that a penny, tossed down at random, will land on a particular ant crawling somewhere along the road from New York to San Francisco. You are lucky to be alive and so am I.
