Although a sceptic about most supernatural manifestations (fairies, angels, gods, ghosts) I do keep an open mind about the possible potential of the human mind to transmit messages, whilst alive. We are now seeing such advances in finding ways to help people 'think' movement into paralysed limbs that it appears the brain is more complex than was ever dreamed of. Perhaps some people can emit brain waves, or pick up those from others, when they are on 'the same wave length'. Perhaps some thought waves could even remain in the ether for a time after death. I find it much more likely, though, to think of the brain as electrical circuits, and once the dynamo stops charging, it just a lump of grey matter.
What I find amusing is that every medium claims to have such a bizarre 'spirit guide' - why do they all have Native Americans, instead of dead plumbers from Salford connecting them to the other world? And anybody who regresses finds they have been an Arabian princess. I am quite sure that I come from a long line of English and Irish working class losers.
