“Around 10-20% of people who undergo NDEs report this flashback of memories and recollection or recall of life experiences or family,” Vicente adds.
During death, your body's vital functions stop entirely. Your heart no longer beats, your breath stops and your brain stops functioning. Studies suggest that brain activity may continue several minutes after a person has been declared dead. Still, brain activity isn't the same as consciousness or awareness.
The waves emitted by the dead patient seem to suggest that, just before the heart stops and up to 30 seconds later, experiences like those reported by many survivors of near-death situations are triggered in the brain, i.e. (usually positive) memories and visions of their lives.
One of the wildest innovations is “living funerals.” You can attend a dry run of your own funeral, complete with casket, mourners, funeral procession, etc. You can witness the lavish proceedings without having an “out-of-body” experience, just an “out-of-disposable-income” experience.
Death just became even more scary: scientists say people are aware they're dead because their consciousness continues to work after the body has stopped showing signs of life. That means that, theoretically, someone may even hear their own death being announced by medics.
What happens when someone dies? In time, the heart stops and they stop breathing. Within a few minutes, their brain stops functioning entirely and their skin starts to cool. At this point, they have died.
They might close their eyes frequently or they might be half-open. Facial muscles may relax and the jaw can drop. Skin can become very pale. Breathing can alternate between loud rasping breaths and quiet breathing.
The immediate aftermath of dying can be surprisingly lively. For the first few minutes of the postmortem period, brain cells may survive. The heart can keep beating without its blood supply. A healthy liver continues breaking down alcohol.
Gasping is also referred to as agonal respiration and the name is appropriate because the gasping respirations appear uncomfortable, causing concern that the patient is dyspnoeic and in agony.
“First hunger and then thirst are lost. Speech is lost next, followed by vision. The last senses to go are usually hearing and touch.”
In the last hours before dying a person may become very alert or active. This may be followed by a time of being unresponsive. You may see blotchiness and feel cooling of the arms and legs. Their eyes will often be open and not blinking.
Hours Before Death Symptoms
In the final hours of life, your loved one's body will begin to shut down. Their circulatory and pulmonary systems will slowly begin to fail. This may lead to falling body temperatures, but may also cause sudden outbursts.
They may experience hallucinations or delusions. They may imagine being with loved ones who are long gone or even believe they are in a different time and place. You may overhear conversations they have with someone they “see” who is not physically present. Your loved one's eyes may stay closed even when awake.
Emotionally: Sadness, anger, disbelief, despair, guilt and loneliness. Mentally: Forgetfulness, lack of concentration, confusion and poor memory. Behaviourally: Changes to sleeping patterns, dreams or nightmares, or to your appetite. You might or might not want to go out or be around people.
This difficult time may be complicated by a phenomenon known as the surge before death, or terminal lucidity, which can happen days, hours, or even minutes before a person's passing. Often occurring abruptly, this period of increased energy and alertness may give families false hope that their loved ones will recover.
Shallow or irregular breathing
As the moment of death comes nearer, breathing usually slows down and becomes irregular. It might stop and then start again or there might be long pauses or stops between breaths . This is known as Cheyne-Stokes breathing.
Does everyone get pain when they are dying? No – not everyone gets pain in their last weeks, days or hours of life. Some people have no pain at all. However, we know that many people with a terminal illness do experience pain.
There are no legal rules about who must be notified when someone dies – the executor or next of kin takes on the responsibility. Employees, including casual employees, are entitled to 2 days of compassionate leave when a member of their immediate family dies or suffers a life-threatening illness or injury.
The first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. As soon as blood circulation and respiration stop, the body has no way of getting oxygen or removing wastes. Excess carbon dioxide causes an acidic environment, causing membranes in cells to rupture.
This discovery held true for both men and women. A previous study from 2008 drew a similar conclusion, finding that surviving spouses had up to a 90% chance of dying within the first three months following the death of their spouse.

As such, a dead person coming back to life would not reinstate a marriage (or invalidate a subsequent one), because the resurrected spouse had died, thus ending the marriage. The same argument could be made for insurance policy payments.
Some people feel better sooner than they expect. Others may take longer. As time passes, you may still miss your spouse. But for most people, the intense pain will lessen.
