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.

      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.

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

            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.

            It’s not rational. Evolution has hardwired us and every other organism that has the necessary neural architecture to fear death and seek to avoid it. A species that didn’t have an instinctive and heritable aversion to death would not last very long.

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

          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.

        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.

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