Consciousness is often said to disappear in deep, dreamless sleep. We argue that this assumption is oversimplified. Unless dreamless sleep is defined as unconscious from the outset there are good empirical and theoretical reasons for saying that a range of different types of sleep experience, some of which are distinct from dreaming, can occur in all stages of sleep.

Sleep is NOTHING like death. You're still experiencing lots of stuff, you still very much have a sense of self, you're still thinking things, your brain is still processing lots of information.

General anesthesia - now THAT is a real close period to what being dead is.

[–] Manifish_Destiny@lemmy.world 110 points 1 year ago

You sound a lot like a guy who isn't dead. Not sure if I should trust your opinion.

[–] Lorindol@sopuli.xyz 71 points 1 year ago (8 children)

I've had general anesthesia, it was just like falling into a deep, dreamless sleep.

If death is like that, then there's absolutely nothing to be afraid of.

[–] Vigge93@lemmy.world 30 points 1 year ago

Probably is. If they gave you a little too much anesthesia so you didn't wake up, you would probably drift off the same, and then just not wake up.

[–] TrustingZebra@lemmy.one 27 points 1 year ago

It's not sleeping I'm worried about, it's not waking up.

[–] BastingChemina@slrpnk.net 14 points 1 year ago

For me when I had anesthesia I quickly closed my eyes with the surgeon talking, when I opened my eyes the surgeon was still talking so I was wondering when the surgery would start.

Of course when I opened my eyes it was 5 hours later and after the surgery but it took me a while to realized that.

Except the agonizing pain which precedes death

Saying "you too" to the waiter after he says "enjoy your meal sir"

[–] JackGreenEarth@lemm.ee 11 points 1 year ago (1 children)

If it's death from too much anaesthesia (or, apparently, freezing), there is none.

[–] insomniac@sh.itjust.works 3 points 1 year ago (1 children)

Is there a way to actually know that?

[–] JackGreenEarth@lemm.ee 8 points 1 year ago

Is there a way to actually know anything?

I’ve had general anesthesia, it was just like falling into a deep, dreamless sleep.

What if anesthesia actually just blocks your memories and physical reactions, but you actually experience everything that happens to you in absolute terror?

Latest studies with FMRIs and other tools have found that general anesthesia decouples the sections of the brain from each other. All the various parts of the brain stop communicating. It's an entities different state than sleep based on the brain activity.

Normally when we have various stimuli or are asleep, neural activity "flows" around from one section to the other. When under general anesthesia those flows are isolated and don't connect to other sections of the brain.

This has actually given us a huge clue as to where consciousness comes from and what makes it a thing.

It also helps explain why going under is just lights out and no drama or anything. It's like an off switch for the "person".

[–] kevinbacon@lemmy.world 4 points 1 year ago (2 children)

Thats exactly what some do, depends on the anesthetic, but it doesn't matter because if a memory never forms it may as well not have happened.

[–] SpaceCadet@feddit.nl 3 points 1 year ago (1 children)

if a memory never forms it may as well not have happened

That is an interesting philosophical question.

If suffering is not remembered, was there even suffering? And if there was, does it matter? I can think of a few counterexamples of that, for example: a killer who tortures his victim before killing them.

[–] pinkdrunkenelephants@sopuli.xyz 0 points 1 year ago (1 children)

Uhh, yes and yes? What's stopping a rapist from anesthesizing their victims before the act and using the fact that they did as an excuse to get off charges under your logic?

[–] jarfil@lemmy.world 2 points 1 year ago (1 children)

Physical abuse tends to leave some physical consequences. You'd have to come up with an example where there would be neither physical not psychological consequences... but even getting anesthesized against one's will is already a consequence.

[–] pinkdrunkenelephants@sopuli.xyz -1 points 1 year ago* (last edited 1 year ago) (1 children)

No it doesn't, not always. Actually it's routine for medical students to be brought in to give anesthesitized women pelvic exams without their knowledge and consent, and no one was the wiser until universities that did this announced it... https://www.nytimes.com/2020/02/17/health/pelvic-medical-exam-unconscious.html

That is textbook rape right there, and it doesn't often have physical consequences. Most women didn't even know but doctors fucking did it anyway.

How you people have any faith in any aspect of society is beyond me.

EDIT: And now I'm being downvoted over it. Imagine being downvoted for pointing out rape occurs during surgical procedures, a well-established fact. Think about the implications of that

[–] jarfil@lemmy.world -1 points 1 year ago

That article is a mix of several cases.

One of those you might call going against the wishes of the patient... then again, that's quite common in the ER, patients are yet to be established as "sound of mind" and capable of deciding for themselves, so an ER doctor can overrule them, including sedating to perform any procedures they consider necessary.

Others seem like letting students perform a non-vital part of a procedure, which is both expected from University/teaching hospitals, and in my personal experience was spelled out in the consent form (although they never told me personally, so if I hadn't read it, I wouldn't know).

That is textbook rape right there

None of those are. Communication could be improved, and I personally get pissed when medical personnel switches from "medical adult talk" to "patient baby talk" right in front of me... but I've also seen patients get upset because they didn't understand what was being talked about, and had to be calmed down with "baby talk"... so it's a difficult issue overall.

[–] jarfil@lemmy.world 1 points 1 year ago (1 children)

There was a case of a guy, where they botched the anesthesia, and he was just paralyzed but conscious the whole time during some invasive surgery. They realized their mistake, and tried to fix it by giving him some amnesic so he wouldn't retain the memories.

After getting discharged, he wouldn't remember anything... but kept having nightmares, and a few weeks later took his own life.

So it seems like memories don't need to be fully formed to mess one up.

[–] kevinbacon@lemmy.world 2 points 1 year ago

That sounds like the mechanism might be different though, but yeah some percentage of people wake up during surgery while the paralytic is still in effect, they closely monitor the heart rate for sudden spikes because of this I believe. It sounds horrifying to me, but then I remember that there was a time when anesthetics didn't exist.

[–] NikkiDimes@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

I had to be put under a few years ago to extract wisdom teeth and I wouldn't say I was 100% gone. I remember seeing the light through my eyelids, hearing muffled unintelligible voices, and feeling mild tension as they worked in my mouth, jostling my head around. No pain, but notable light sensations. It also felt like it was over in a minute for an hour and a half procedure. Was definitely a wild experience, but certainly no terror remembered, thankfully.

[–] Croquette@sh.itjust.works 7 points 1 year ago (1 children)

I think that most people aren't afraid of death itself. It's more the suffering to get there.

[–] ezures@lemmy.wtf 4 points 1 year ago (1 children)

The most scary stuff is just not doing or experiencing anything after death, at least for me. (Probably the biggest fomo on earth)

[–] Croquette@sh.itjust.works 3 points 1 year ago* (last edited 1 year ago)

Life is a series of missed opportunities. When you choose to do something, you miss out on a multitude of other options. That is fine.

But I get the FOMO, it took me a few years of active mindfulness to reign it in.

[–] Kodemystic@lemmy.kodemystic.dev 7 points 1 year ago (2 children)

But isn't there a fear anyway? Because its forever. Also not seeing loved ones ever again. Not enjoying the nice things ever again.

[–] jarfil@lemmy.world 3 points 1 year ago

Add constant pain, and that's what I call life.

[–] zeppo@lemmy.world 5 points 1 year ago

What’s hard for me to accept is the idea of never waking up. It seems like it has to end sometime.

[–] newIdentity@sh.itjust.works 5 points 1 year ago (1 children)

Well except Ketamine and some other substances that are used in anesthesia.

[–] LanternEverywhere@kbin.social 9 points 1 year ago (1 children)

That's not general anesthesia, that's like twilight anesthesia or some other term like that.

[–] Telodzrum@lemmy.world 8 points 1 year ago

Conscious sedation is the term of art. Fentanyl and versed are commonly used for this tour of sedation.

[–] Anamnesis@lemmy.world 3 points 1 year ago (2 children)

When I'm asleep I'm not experiencing shit. Close eyes, moment of black, awake again the next day.

[–] grozzle@lemmy.world 5 points 1 year ago (1 children)

This is not the normal human experience. Check if you're a robot?

[–] bingbong@lemmy.dbzer0.com 1 points 1 year ago

My diagnostics said "all systems normal" so that can't be it

[–] samus12345@lemmy.world 4 points 1 year ago (1 children)

You just don't remember your dreams.

[–] Anamnesis@lemmy.world 2 points 1 year ago

That's probably true. I have definitely had some dreams. But maybe only fifty over thirty-seven years.
