A near-death experience (NDE) refers to a range of personal experiences associated with impending death.

The experience is often described as involving a feeling of extreme peace, a sound similar to a bell or a buzz, a passage in the darkness, then a transition to the light.

However, little research in this field indicates that these feelings happen if the patient get in situations that affect the state of the brain, such as cardiac arrest and anesthesia. The conditions that lead to a state of near-death appear to significantly affect the nature of experience. Still, many people who had near-death reports are similar. These are usually caused by the use of psychotic (due to severe neurochemical imbalances) or drugs such as hashish or LSD.

Believers think that NDEs prove the existence of life after death. Skeptics think that NDEs can be explained by neurochemistry and are the result of changes in a dying brain.

Patients sick or dying, victims of traffic accidents or drowning include, in detail, how it feels to be on the other hand, a process that is believed to be of a first step after the end of life.

The NDE has received the attention of medical experts around the world. Most people surveyed experienced physical and psychological trauma that would lead to so-called physical death was not the manifestation of chance. Not rare are the stories of doctors who found patients dead and, minutes later, were surprised by the resuscitation from the resumption of vital signs.

In the so-called astral travel or projection, the experimenters of the NDE tell they met strangers or relatives already dead. They have in common the memory of the appearance of a white light and reported the possibility of seeing their bodies at an angle close to ceiling - a few meters away from where the physical body was.

For science, the phenomenon can be explained as an effect of pharmacological substances mixed in the treatment of patients in ICUs. There are also those who believe that the experience might be related to neurological or psychological problems, or self-suggestion. However, even the experts admit that there are phenomena that science has yet to unravel.
