Life after death: Discovery could explain mystery of near death experiences | Science | News


Researchers found those who have suffered an NDE often have irregularities in their deep sleep state.

The study analysed 55 people who had been in a “life-threatening episode of danger”, such as a car crash or heart attack, when a person experiences a variety of feelings. These include a sense of being outside of one’s physical body, unusual alertness, seeing an intense light, and a feeling of peace.

It also looked at 55 people who had not had an NDE.

The research found the people with NDEs are more likely to have a condition called REM-intrusion which sees individuals struggle to differentiate between just waking up and a dream – or when a state of sleep intrudes into wakeful consciousness.

A statement from the University of Kentucky, which carried out the study, states: “Examples of this REM intrusion include waking up and feeling that you cannot move, having sudden muscle weakness in your legs, and hearing sounds just before falling asleep or just after waking up that other people can’t hear.”

The research found 60 percent of people who have had an NDE have reported REM intrusion, whereas just 24 percent of those who have not had an NDE.

Neurologist and study author Kevin Nelson said: “These findings suggest that REM state intrusion contributes to near death experiences.

“People who have near death experiences may have an arousal system that predisposes them to REM intrusion.”

Dr Nelson added that other factors also support his theory.

For example, the feeling of an outer body experience has also been linked to the REM state and “the feeling of being surrounded by light could be based on the visual activity that occurs during the REM state”.

REM states can also cause muscles to completely relax.

Dr Nelson added: “During a crisis that occurs with REM state intrusion, this lack of muscle tone could reinforce a person’s sense of being dead and convey the impression of death to other people.”
