There is no generally accepted definition of a near-death experience. NDE definitions have been used with some variability for more than 35 years, Long writes. Although no two NDEs are the same, there are characteristics that are commonly observed in this case.
These characteristics include seeing and hearing outside of the physical body, going into or through a tunnel, encountering mystical light, intense and generally positive emotions, reviewing some or all of one’s previous life experiences, encountering deceased loved ones, and the choice to return to your earthly life.
During a long study, the expert collected 9 evidence in favor of the fact that near-death experiences are real.
Considering NDE both medically and logically, unconscious people should not often report very clear experiences that are logically structured.
Therefore, the scientist believes, it works in favor of the reality of this experience.
“Near-death experiences often occur in connection with cardiac arrest. Previous studies have shown that 10-20 seconds after cardiac arrest, electroencephalogram measurements typically do not detect significant measurable electrical activity in the cerebral cortex.
“Prolonged, detailed, conscious experience after cardiac arrest should not be possible, but this is reported in many NDEs. This is especially noticeable given the long period of amnesia that usually precedes and follows recovery from cardiac arrest,” Long explains.
Seeing current events from a place other than the physical body in an unconscious state (out of body experience)
A common characteristic of near-death experiences is also out-of-body experience – this is an obvious separation of consciousness from the body.
About 45% of those who experience see and hear current earth events from a vantage point that is separate from and usually above their physical bodies.
After cardiac arrest, the people interviewed saw and then accurately described their own resuscitation.
Near-Death Experiences with Vision in the Blind and Supernatural Vision
Vision in near-death experiences who are blind, including those who are completely blind from birth, has been described in many case reports.
This, along with the conclusion that vision in NDE is usually different from normal everyday vision and is often described as supernormal, also suggests that NDE cannot be explained by our current understanding of brain function.
Near-Death Experiences Under General Anesthesia
Under adequate general anesthesia, it should not be possible to have a clear, organized memory, Long emphasized.
This is shown by studies using EEG and functional brain imaging of patients performed under general anesthesia.
They provide substantial evidence that the brain under anesthesia should not produce conscious memories.
Near-Death Experiences and Life Reviews
Some near-death experiences involve a review of some or all of their previous lives. Life review may include awareness of what others felt and thought at the time they interacted with them.
This previously unknown realization of what other people felt or thought when they interacted with them is extremely surprising.
Encountering Deceased Loved Ones in NDEs
NDEs can describe encounters with people they knew during their earthly lives. It is noteworthy that people who saw a person they thought was alive, in fact, had recently died, reported cases.
These cases illustrate that NDEs cannot be explained by the experiencer’s expectation of what will happen during the life-threatening event.
Near-Death Experiences in Young Children
Very young children have near-death experiences that are strikingly similar to those of older children and adults.
This is further evidence that NDEs occur independently of pre-existing cultural beliefs, religious training, or awareness of the existence of NDEs.
Cross-cultural NDE research
The absence of significant differences in NDE content worldwide is consistent with the concept that NDEs occur independently of physical brain function as currently understood. Thus, the experience does not depend on the place of residence, religion and other factors.
Near-death experiences after effects
After near-death experiences, there are usually significant changes in people’s lives, which are called the consequences of the event.
Notably, NDEs often occur within just a few minutes of unconsciousness, but usually result in significant and lifelong transformations in beliefs and values.
“A combination of the previous nine lines of evidence converges to the conclusion that NDEs are medically inexplicable. Any one or more of the nine lines of evidence would probably be strong enough for many, but the combination of all of the nine lines of evidence presented provides strong evidence that NDEs are, in a word, real,” the MD concluded.
