Reports of after-death experiences are nothing new, but they seem to becoming more and more common in recent years. Individuals who have suffered serious injuries and been pronounced clinically dead have sometimes regained consciousness, and upon returning, told of strange sights that they saw while in this altered state.
To make things more interesting, the descriptions of these experiences often share many things in common. Such experiences happen when the person has no pulse or breathing pattern, which means that according to medical science, they can be considered dead.
People in these situations often see visions of light as well as their loved ones and family members. The whole experience is said to be relaxing and peaceful; people often describe being in a tunnel as well.
It’s easy to see why some people feel that these experiences must have some basis in reality. How could so many people have the same experiences otherwise?
The scientific community isn’t convinced, however; doctors say that these experiences are perfectly explainable by human biology and neuroscience. The lack of blood to the retinas, they say, causes the tunnel vision, and the brain chemicals released as a result of the stressful situation are responsible for the other phenomena.
Many of those who have had these experiences, however, insist that what they saw was absolutely real.
Wherever the truth lies, it may be some time before we know what truly causes these experiences. We may never even know for sure at all, since we may have to pass on ourselves before we know the truth behind near-death experiences.
In the meantime, doctors and scientists will continue to study these experiences, as they present a very interesting example of a part of our world that has yet to be explained for sure.
