The debate about what happens after death has continued for thousands of years and has been guided by science, religion and philosophy. But thanks to advances in medical technology, scientists are now getting a clearer picture. One of these scientists, Dr. Sam Parnia, Head of Cardiopulmonary Resuscitation Research and Assistant Professor at the Stony Brook University School of Medicine, believes that he has found evidence that people know when they are dead.
In a case study of 140 people who survived cardiac arrest events, many felt the sensation of death and knew what was happening around them.
Dr. Parnia said, "They will describe how doctors and nurses work, they will know that they are aware of the full conversations and visual things that were going on that they would not otherwise know."
Dr. Parnia's AWARE or AWAreness during resuscitation, study, details: "Survivors of cardiac arrest (CA) suffer from cognitive deficits including post-traumatic stress disorder (PTSD).
"It is unclear if these are related to cognitive / mental experiences and awareness during resuscitation.
"Despite anecdotal reports, the broad spectrum of cognitive / mental experiences and awareness associated with CPR has not been systematically investigated."
Of the 140 respondents, 46 percent had "memories of 7 major cognitive themes: anxiety; Animals / plants; bright light; Violence / persecution; Déjà-vu; Family; Retrieve events[cardiac arrest]".
Two percent "described the consciousness with an explicit memory of" seeing "and" listening "to the actual events associated with their resuscitation, with a demonstrable time of conscious awareness during which no cerebral function was expected."
Dr. However, Parnia recently said to Oz Talk, "People describe a sense of a bright, warm and inviting light that brings people to it.
"They describe the feeling of experiencing their deceased loved ones almost as if they welcome them. They often say that in many cases they did not want to come back, it's so comfortable and it's like a magnet that attracts them, they do not want to come back.
"Many people describe a sense of separation from themselves and the observation of doctors and nurses working on them."
Dr. Parnia says there are scientific explanations for the reaction, and says seeing people is not evidence of life after death, but rather the brain, which scans itself as a survival method.
Thanks to modern technology and science, he said, "Death need not be limited to philosophy and religion, but can be researched by science."
He added, "You can hear things and record all the conversations that take place around them."
