I'm sorry that happened to you. That's so horrible. Wanna make me beat up bullies, man. Got damn bullies.

I do have dreams of beating up bullies. Count me in.

There were times over the years I played the waiting game and got back at certain bullies. Each time I got in a heap of trouble, but always recovered my pound of flesh.

Not exactly the topic - but I went through a strange consciousness bottleneck during a near death experience (in risk terms, not in the medical death sense), in which I was extremely lucky.

A car I was driving to a parking area for someone had incredibly loose steering, and I lost some traction on a tight turn on a country highway that had been covered with gravel. As I straighten out of the turn I was heading straight at an oncoming car.

I calmly jiggle the steering wheel to avoid the head-on collision, with as little adjustment as possible to avoid losing control, but the car fishtailed anyway, hit a rock cliff wall on the right, bounced 45 degrees and off a short cliff on the left side of the road.

As I went off the cliff I just thought calmly "So that was it.". At the same moment, not having had the sense to be wearing my seatbelt I threw myself flat across the unified front seat.

The car went over the cliff, hit it, flipping end over end and then rolled before coming to a stop, upright, facing the opposite direction I had been driving, completely destroyed.

Technically, I never lost conscious, but from the moment the car launched I lost all awareness except for sound. My mind absorbed endless crashing, metal rending, glass shattering, 10 or 20 seconds of silence, and then I suddenly had vision again, and a sense that I was still in my body. Calm, with normal physical sensation, and no pain.

I was incredibly banged up, but couldn't feel any of it. I moved my limbs and body carefully, guessed I was ok to travel, crawled out a missing window and sat on the bottom slope of the drop until help arrived - the oncoming driver happened to be a medic. I was so calm and lucid people expected me to stand up and find my way up a navigable part of the slope with them, and so did I. But while I had been sitting and talking without effort, I couldn't get a single muscle to actually move. When my legs wouldn't move, I tried raising an arm and it just didn't respond. I had to tell people I couldn't move, because there wasn't any evidence I was trying.

Bruises of the steering wheel around my body, and other lacerations formed a visible record of my body being thrown around in complete mayhem. But all I retained is a clear disembodied memory of endless crashing, eventual silence. Without any fear or emotion, beyond a feeling of acceptance that morphed into interest in what had happened.

Nothing broken - no stress or post-stress, despite a couple weeks of miserable pain and soft tissue recovery. I could be wrong, but I don't think my heart rate or breathing adjusted at all.

Apparently, I survived in part by being completely relaxed the whole time.

> On the spiritual side, I think it is somewhat calming. I face this at times when you have patients that pass away and you talk their families; you have to be the bearer of bad news. Right now, we don't know anything about what happens to their loved one’s brain when they're dying. I think if we know that there is something happening in their brain, that they are remembering nice moments, we can tell these families…

Spiritual perhaps in that it satisfies a need that cannot be provided by material comforts or by the mere intellectualising of it?

No. As an aside, when you are younger they may elect to put you into a twilight level of sedation. And that is how I saw the inside of my own beating heart at 10 while I was tied down and essentially naked in front of like 10+ adults. Oh, and the contrast dye momentarily made me feel like I was being burnt alive from the inside out.

My wife had this done when doing a biopsy, IIRC, and it scarred here / gave her PTSD for years.. She now insists on full sedation.

That's more than fair I'd say.

So is it similar to dreaming? Also, what do you mean by "sound"? Like music or actual sound from your memories?

Part of it has to do with the memories, which gradually gets overtaken by the voices of my wife, doctor or whomever was trying to wake me up. As an example, I think I was around 16 years old and I was very much into sport cycling and Tour de France. When I lost consciousness a slide show of Tour de France competition accompanied by the TV commentators rush into my thoughts. All of it at very high speed and extremely…

Ha! I like the thought of unconciousness triggering a "kernel OOPS" and the brain dumping out a backtrace of everything. Makes you wonder who is supposed to debug it later ...

Had the same experience, what scared the crap out of me is that feeling of not even knowing you're out is how some people spend their last moment. Not just in surgery for example but in extreme other situations (nukes, titan sub, piano to the head, etc)... You're just there then you aren't and you don't even know. Shook me (lightly) for a while

Honestly it doesn’t sound too bad to me. Just blinking out of existence. No pain, no regret. So what’s there to be scared of?

Dying is generally pretty easy. It’s hardest on those left behind.

I don't think fighting back is shitty in any way. a) Either there is no objective morality and then anyone can do anything they can justify using their personal moral system, as long as it's internally consistent (it blatantly isn't for most people and perhaps subtly isn't for the rest) b) or there is objective morality and then anyone can dispense punishment (for example by fighting back) because there's no reason t…

This is a really good post that people should reflect on. There is something particularly dark and unjust about supporting the persistance of tyranny through the blaming of (solely or not) those who defend themselves.

Imagine telling kids that not only should they not defend themselves, but that they should also pay for the bullies groceries and electricity.

Most bullies just vent out what they suffer at home, school or workplace. They already punish themselves by not reacting against the real source of their problems.

Clarification: I never justified what bullies do, just giving an explanation. I should have made more explicit that punishing alone accomplishes nothing if the source of the problem isn't addressed: they just go to the next easier victim.

Humans react differently or have different tolerances, for example my teeth are very sensitive to pain and I needed extra adrenaline to fully numb it, even though I don't take drugs or have anything indicating that this would be necessary.

> extra adrenaline to fully numb it, That's not what they usually use... but people have different reactions to novacaine, and different innervation; for dental work, there's a couple typical options for where nerves are and which nerves cover which teeth, some of which need more shots in more places. For the GP, most likely the anesthetist put a note in the chart that they need more or different drugs to go under.

I'm from Germany and adrenaline is used as an addition as a vasoconstrictor here. There are quite a few differences between countries when it comes to anesthesia.

Finally growing up big enough and successfully beating up a bully was one of the best memories of childhood I have...
