If ghosts are the spirits of deads, as many people believe. How can we explain the apparitions without a "soul"- those of animals and unanimated objects?
It seems to me that an explanation is possible and acceptable for animals. Despite of not have a "soul" as such, animals are living things as well as plants.
Taking of ghosts, it was almost impossible not naming the case of the London "ghost" bus in the thirties.
It was a big red bus, having the number "7" which harassed motorists in the section of Kensington North. The joining point of the boulevard
Saint-Mark with the gardens of Cambridge, this zone, had been taken for long as a dangerous corner. From both sides, it was impossible to see anything that was coming from the other side- it had been the cause of many accidents.
The decision from local authorities to set upright the curve was partly influenced by motorists who used to take the road in the
night and claiming to have seen the red bus.
Among the most impressive testimonies, there was an employee of the bus company claiming that he saw the vehicle coming back to the company garage at dawn, it stopped and the motor ran for a few more seconds then it disappeared.
The mystery was never resolved but it is significant to consider that no one ever saw the bus after that the danger of the acute angle was withdrawn.
