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)

          I won’t be around anymore to experience those consequences so I’ve never felt particularly afraid of them. Why fear something that will never happen to me?

            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.

              Definitely. I’m usually averse to death or dying, but I wouldn’t describe it as fear. Wishing to avoid an outcome isn’t always the same as fearing said outcome. Not in the same way I might fear pain

              My sense of self preservation is somewhat compromised so I’m probably not the best example

                Describe your “aversion” to death any way you want to, if in the end it results in something that very much looks like fear, I think you’re making a distinction without a difference.

                  A preference against it occurring. I don’t like slow jazz so I’d rather not listen to it. I don’t want to die at the moment so I’d rather not
