Your brain hallucinates your conscious reality | Anil Seth

  • Published: 18 July 2017
  • Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

    If I had a nickel for every Jewish shill who claims there is no reality, I might be as rich as they are. If you believe you are not supposed to believe your own God-given five senses, there is no hope for you.

          They do not take people serious after use the word hallucination. But what you see is real. People do not hallucinate.

                I'm reading that you don't know where you liver is, I heard the speaker say that he doesn't know where his spleen is. Listen again. Hmm, the speaker made an excellent point.

              You couldn't be more WRONG about life not being due to some life force essence. It's called the SPIRIT, and without it, the body is completely dead, even though that body still has ALL of the DNA and Neural Networks and chemistry it had before death! What's the difference? Simple, a living body has this mystical life force "SPIRIT" The dead body does not! If as you claim science knows life is simply due to chemical motion then we should have created life in a laboratory by now, and yet, brilliant scientists have attempted and failed to this present time even to create the simplest life through isn't Chemistry that is the spark of is the SPIRIT! The most we have ever made in lab were very basic amino acids and they were all of the right handed type, yet in biological organisms all amino acids are of the left handed type, so even the basic amino acids created in lab were the completely wrong types! Again...WITHOUT THE SPIRIT (True source of consciousness and awareness of self) There is NO LIFE even with all the necessary chemistry present and even put together! By the way consciousness is NOT dependent upon having a body either. Consciousness doesn't end, because it's source is eternal...therefore it also is eternal.

                  "When the end of consciousness comes, there is NOTHING to be afraid of" Based on everything you just said, which was extremely smart, until you got to this part, it became contradictory. You have no way of knowing that. You can create ways of knowing it, but the unfiltered, non-hallucinated truth will remain as it is.

                      I was recently on a flight from Thailand and as I slept I dreamt that I was driving my car and a rocket was flying overhead. I believe because of the roar of the aircrafts engines my mind used its best guess to determine the source of this sound and expressed this as the rocket in the dream

                              Thats how it looks, when you get lost on a completely wrong path. There is no self and the world. Thats also just an illusion the brain creates. There is only conciousness and conciousness is prior to everything. Conciousness doesnt get created, conciousness creates everything. The brain trying to figure out what conciousness is, is like a hammer trying to figure out, what swings it by looking at the nail. The approach of Anil Seth is hopelessly bound to end up in frustration.

                                  The brain is a physical thing we can weigh, measure and hold. The mind is not. Energy is physical, but the mind, our very thoughts are something else we cannot explain. I don't think that our minds hallucinates anything but perhaps our brains do since they are part of this physical realm we live in. Our minds are able to imagine ourselves traveling out of this solar system yet or physical brains do none of this. This doesn't explain anything and leaves more questions then answers.

                                    So there’s no way to prove what is real and what isn’t then? This could really just be a mass hallucination? I mean it doesn’t feel real, it never has. I’ve never felt like a part of anything, in control of anything, just like a watcher using this thing that’s supposed to be me to try to interact with the things around me. Trying to make sense of it all, asking questions about everything until I shut up about it because clearly I’m just an idiot that doesn’t get anything. But to me there has never been much of a difference between dream and awake, they are just two different places, that’s all.

                                                  I JUST started watching "Seth" converse and I'm gona stop here and watch this later. I'm extremely curious about when people start to "die" and what they experienced; those who've lived through it. I almost died 2-15-13. And it was the 1st time in my life I hallucinated, 5xs exactly. I "knew" what I was seeing wasn't real. But I also knew that they were "things" in real life I either hated or had a scare from. Not much in my life has ever scared me, I grew up tough. But these hallucinations I was able to shrug off quickly. It was the last hallucination which was auditory the really surprised me and saved my life! Till later...

These comments are quite depressing. I was hoping to find intellectual consideration of the topic instead of imbecilic examples of what they presume this to be about. It's as though people heard hallucinations and just ran with it.

                                                            Lets assume that our body is only a perception from within and we make it a reality. So why is it that we all have the same hallucination as to where our organs are placed? Everybody has a heart in the same place. Is it possible that if we are hallucinating our reality, (which i believe) we are all hallucinating the same thing, like some type of collective hallucination?
