What happens to you just before you die? Chemists explain exactly how death feels
A quick jolt of fear, pain — and then a mysterious process that sees the brain have an extra jolt of life just before it dies forever
VIDEO:

Slasher films are a lot of fun to watch. But what exactly would it feel like to get stuck in one?

Scientists have explored many of the things that happen to the body and the mind as it approaches death — and while much of it still remains mysterious, the experience can be understood through the various chemical reactions and events that are happening in the brain.

Just in time for Halloween, a new video from the American Chemical Society explores exactly what would be happening inside someone’s body as they are being chased by a murderer in a slasher film.

The creators of the video point out that the experience of watching people get chased through a slasher film is actually similar to being there — though the actual thing is presumably a little more intense. The same sense of adrenaline and fear is activated in the same way in both cases.

The function of fear is to get people ready to react, or run away. It is a way of alerting the mind and body about trouble, but it is also a chemical process that allows the body to try and be safe.

The sensory information is sent through a person’s central nervous system, and into the thalamus, which works a little like a switchboard. That’s then transmitted to other important parts of the brain.
That information initially makes a person startled — moving towards getting them ready to react. And then the fight or flight response is triggered, which begins a process that began in our very early ancestors as a way of deciding whether to take on an attacker or try and escape.
That process pumps out adrenaline through the body, and pushes out glucose through the blood stream. Other chemicals keep those processes working.

You might not get away from the axe murderer or whoever else is chasing you down. In which case, you’re likely to start screaming.
The video points out that process originates in a different part of the brain from language, and serves a different function.
Screams come out almost by instinct. And when they are heard, they trigger a similar response — encouraging other people to become fearful and react, and so presumably helping them run.

If the screaming doesn’t help, and your axe murderer catches up with you, you’re going to be in a lot of pain.
When you’re injured, special neurons called nociceptors send messages up to the brain. Those are collected by the thalamus — which in turn tries to instruct the brain to do whatever it can to stop the injury happening again.

Even after clinical death, your brain probably keeps ticking on for a while. According to recent studies, the brain appears to undergo a final surge — in a way that would normally be associated with consciousness.

It may be that the surge might be responsible for near death experiences. Studies have supported that hypothesis — though scientists are still entirely unsure why the surge happens, or what it signifies.


Then comes biological death. And it’s not clear what happens then…
There’s little way of knowing what happens after all that is over, because people tend not to come back.
But some have. In an Ask Me Anything session earlier this year, people described their experiences of having briefly passed away.

“"Pure, perfect, uninterrupted sleep, no dreams,” wrote one.
But others described more vivid experiences that apparently hinted at an afterlife.

"I was standing in front of a giant wall of light,” wrote another. “It stretched up, down, left and right as far as I could see. Kind of like putting your eyes 6" from a fluorescent lightbulb.
“The next memory I have is waking up in the hospital."

The most interesting bit here, about 'brain surges', I've bolded in the piece above. It would have been good to get more detail.

"No wonder. He would have been the last person she was expecting to see! "

Surely he wouldn't have been the last person she was expecting to see? There must've been hundreds, thousands, of less-likely contenders. The relative ranking of them all might be challenging...

But this....is solid gold: Peter, 42, said: "I'm glad to have helped this lady recover in some way."

When what he should've said was 'Please....it was nothing'. It opens the Pandora's Box of unattributable accolades, fictional contributions made in mind only. Latter-day nonsense non-saints, saving us all via osmosis from their aura

Kid suffers severe brain trauma, nearly dies, starts to recover just before he was about to be taken off life support, reports NDE.

He has been walking and talking, even reading and doing maths, Ms Reindl said, calling it "a miracle".

Trenton himself told WALA he thought he was in heaven while he was unconscious.

"I was in an open field walking straight," the 13-year-old said.

"There's no other explanation but God."

I did not have a near death experience, but died multiple times before waking from coma.
When I was gone, I saw present and future in strange ways, I can only explain it as parallel universes, I was shot, bitten by a Ningen and died multiple times of heart failure, which was the reason I was kept comateus for nearly 4 weeks.
All this happened 11 years ago, even now I have moments that I feel dying somewhere and have flashes of strange memories.
In my eyes life moves thru the universes like a multidimensional river delta, sometimes our information spreads out, sometimes it comes together again, at the end our lives come together in one big stream.
Who knows what happens in a 11-dimensional universe.

When I was younger, I came down with Viral Encephalitis, wont go into details but it put me in a coma, during this time my heart stopped, and I still to this day vividly remember a light, then a couple thick Scottish accented voices speaking (my Dad's side are from the west coast). I can't account for it, or explain it away really but I'm certain it was an NDE

What did the Scottish voices say?

From what I remember I couldn't properly make out the others but the clearest one said "He's a fighter, he'll be ok". Mum was told I would be in a vegetative state at the best but to expect the worst, and it turns out possible hallucination voice was right

Was it an hallucination, or was it someone at the hospital?

I have asked my Mum about it and she doesn't remember anyone other than my Granddad being there with a thick Scottish accent, she does remember him saying something similar to what I heard but when getting lunch so nowhere near me at the time. It could have been any number of things, time distorting memory, some kind of hallucination, I've always leaned towards weird hallucination too but it does seem to "fit" some of the other NDE stories I've read

Sounds like a historial NDE here from 563AD (learned via Mike Stuchbery) :

https://en.wikipedia.org/wiki/Oran_of_Iona

One popular legend surrounding Odran's death is that he consented to being buried alive beneath a chapel that Columba was attempting to build at Iona. A voice had told Columba that the walls of the chapel would not stand until a living man was buried below the foundations, and indeed, each morning the builders would arrive at the site to find all their work of the previous day undone. So Odran was consigned to the earth, and the chapel was erected above him. One day, however, Odran lifted his head out of the ground and said: "There is no Hell as you suppose, nor Heaven that people talk about". Alarmed by this, Columba quickly had the body removed and reburied in consecrated ground – or, in other versions of the story, simply called for more earth to cover the body.
