We spend a third of our lives asleep. Every organism on Earth—from rats to dolphins to fruit flies to microorganisms—relies on sleep for its survival, yet science is still wrestling with a fundamental question: Why does sleep exist? During Shakespeare and Cervantes' time, sleep was likened to death, with body and mind falling into a deep stillness before resurrecting each new day. In reality, sleep is a flurry of action. Trillions of neurons light up. The endocrine system kicks into overdrive. The bloodstream is flooded with a potent cocktail of critically vital hormones. Such vibrant activity begs the question: Where do we go when we go to sleep? Based on new sleep research, there are tantalizing signposts. We delved into the one-eyed, half-brained sleep of some animals; eavesdropped on dreams to understand their cognitive significance; and investigated extreme and bizarre sleeping behaviors like “sleep sex” and “sleep violence.”
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

What if your brain practices and tests itself when your sleeping? Like how in non rem sleep the brain compresses and plays memories both forward and backward in time, then in Rem sleep the dreams are as if its happening in real time. What if the brain tries to learn as much in non rem sleep then in rem sleep it practices what it learned from non rem sleep. HOLY FUCK!
World Science Festival I could do German but have never done translations on YouTube. The link looks easy. Would you just want us to give it a go or do you need anything else? All the best. Rudi
Addendum: have just started translating and just went away with it. It is very easy to do but don't see the through the whole process, yet.
I have LUCID dreams most of the time that seem so vivid there real life besides the fact that I can typically fly and I’m in the past at my old house before I moved and it was completely changed to s different floor plan oh I can teleport and manifest things with my mind and breath under water other then that I can feel sometimes taste and smell I can hear and my normally blurry vision is clear
LUCID DREAM-knowing that your dreaming WITHIN a dream and it seems like reality but you’re able to have superpowers that u can’t have on earth
WARNING-the dream characters claim to be real beings on the astral plane (people from earth come there while dreaming and ALWAYS reek havoc) so watch what u do in those types of dreams
I used to get looked at as if I was nuts when I told them I was dreaming or I was told I wasn’t dreaming and it was real life until I asked
I think it's so cool how we can remember our dreams because it's Like we remember something that never happened. I feel like we can force ourselves to have a certain dream to see how it feels to be in that place. I think dreaming is the same as thinking but our brain tries to make it to where we can feel, hear, smell, taste, and hear everything thats going on in our dream so its more realistic
My brain would give away that I am dreaming by making my dream world too sharp.
I could see perfectly for long distances. The colors were too bright. I could read tiny text without my glasses. I could hear sound as if my entire body was a ear.
But recently I have been having dreams were the level of reality is just right and even when questioning if I am dreaming and analyzing my environment I can not tell the difference between dream and reality. The wooden bench looks and feels just right. The smoke puffed out from the man smoking looks just right. The tree leaves and branches looks as it should. Nothing too perfect or too sharp. There is nothing to give away that I am dreaming.
Can be scary when having a bad dream.
Weird thing is when I dream....I feel free....I dont know who I am and I dont care about the problems that I have when I wake up,I am like in an infinite world where my imagination rules and its so relaxing to not care about the irl problems when I fall asleep.
I can’t sleep every time I do I get way into my dreams I can control them and sometimes I can’t and I don’t like it because it’s mainly scary or feeling pressure/chased but very vivid I’d wake up and never wanna fall asleep again
Not to give the wrong idea but my dreams and that world are more meaningful to me and enjoyable than this world (the waking state) while dreaming I can visit and spend time with lost loved ones, fly in the air, help others, and explore, experience, and grow. This has caused me to feel very uncomfortable upon waking up and having to experience this inferior world (the waking state).
your mind goes into different layers than the ones when you are conscious. when you think of it who you are , you realise the memory of things you do everyday and the experiences you have had related to them is you. the live you is constantly changing. the deeper layer that consolidates behaviours stay almost the same during short intervals. it like a abyss where you rarely venture. during sleep our mind just wanders from layers to layers stimulating newer synapses to consolidate the memory. the brain is focussed more than what it is when we are asleep than awake. whatever you experience gets consolidated into your brain during sleep. its like a cloud mode activated.
Think about this: If a person who lives to 100 years old and they sleep 8 hours a day, they will have been awake for 66 years. If some one gets 6 hours of sleep they will have experienced 75 years awake.
Or if you take the average age of death at 80 years and you sleep 8 hours 1/3 of the day you will have lived 53 years while an 80 year old on 6 hours gets to experience 60 years.
Ive chosen to sleep much less over the past year, 5 to 6 hours. In the process i have walked/ran 1410 miles since september and am aiming for 2680 by this September. I have a family of 4 soon to be 5. I am in graduate school for masters degree in business management with an emphasis in leadership. I work 64 hours straight every weekend, am drawing up the bones of my own firm working with homeless people. My creativity and joy have gone up. I value what i have far more than i used to. My energy levels are great.
And my sleep is phenomenal. It takes about 5 minutes to smash into REM sleep, remember my dreams, and then interpret them when i wake up.
Ove also changed my whole attitude towards thjngs in my life and the world around me, and am still practicing.
If any academic researchers are reading this I have a ability that is either supposed impossible or very rare. Or at least was years ago.. I can close my eyes and be asleep within a minute and at the same time go immediately into a dream state.. A ex fiance who used to observe this saw the tell tale rem movement of eyes for confirmation to her.. Myself I also remember all my dreams.. Many I will remember in part, sometimes only in feeling for many years after.. Dream memory follows into dreams meaning I can dream and be aware of a memory of a previous dream within this dream. I have had false awakenings.. I have been fascinated by dreams all my life and would love lucid dreams, I have been close for seconds but never a full dream.. I have been close in that I've thought I'm dreaming ill wake now..usually in startling positions in a dream.. Anyway any researches interested comment and I can email one on one with you concerning this.
In the beginning of this show, I really wonder, what would the interviewed people say about sleep if they had never been exposed to any form of info about sleep. What if there was nothing to regurgitate??? I'm definitely not suggesting there's any wrong in the responses. I just really wonder (even outside of this topic) how would we respond without exposure to data, reports, or other forms of communicated info🤷🏽♀️
Is that the only life this rat gets to experience ?? This small space ? ... i don’t like how we get the information sometimes seems inhumane . That’s how I feel about of a lot of laboratory animals ... it’s so unfair they are forced to live there life being test subjects .never being able to truly Liveor experience a larger life .
Thanks for the video! I believe sleep is crucial to keeping our bodies functioning properly. When I go to sleep, my mind often goes in search of a bathroom with a working toilet inside a house with many rooms. It's never the same exact house, but like a maze that changes each time I have the dream. The urge to urinate or deficate is so strong that I spend what seems like hours opening door-after-door, in a panic, hoping one of the rooms will be a bathroom with a toilet that is not stopped up with toilet paper and/or feces. Sometimes the room will be what appears to be a bathroom, with a sink and a tub, but it won't have a toilet at all. Sometimes the room will be a bedroom where someone is sleeping. When entering such rooms, I immediately wonder if there is a bathroom attached to the room. So, I tip-toe around the room opening any door I see, hoping I will find a toilet. Some doors lead to just closets. Some lead to large living rooms. I feel like a rat in a maze and a working toilet is the exit. Eventually, I get so frustrated at "needing to go", I bolt awake and realize I was just dreaming and that the purpose of the dream was to alert my body to the fact that my bladder or bowels needed to be emptied; at which point, I get up and walk to our bathroom, which has a working toilet....thank God! LOL Afterward, when I return to bed and fall back asleep, such dreams do not return. One time when I was having one of those dreams, I dreamed that I said to myself, "This can't be happening....not being able to find a toilet....so, I must be dreaming." At which point, I woke up.
I don't dream anymore. One time I dreamed that I killed Jesus and Satan. Weird. I also dreamed that I was levitating and I remember saying I don't wanna go to hell. It was terrifying. I remember asking god to not let me dream anymore and boom. I stopped dreaming. Uts weird
I really need help. I find myself sleeping all the time no matter where am at. In my office, in the car, etc. I just can't wake up early enough so am always late to every place. I would actually sleep 24/7 if l have the chance. Is something wrong with me?
My dreams have been totally bizarre lately , its gotten to the point where i have a completely interactive , vivid dream every night. Sometimes i cant even explain it , but i think ive also been experiencing sleep paralysis lately , thats what brought me to this video just now after i woke up lol. ive been told i move and sometimes speak when i sleep too , the dreams started after i got clean from opiates a year ago in march.
I HAD A DREAM THAT WENT WRONG ,I FELL FROM AN ELEVATOR , I HIT THE GROUND AND GOT UP AND SAID TO MY SELF , I SHOULD BE DEAD, I DUSTED MY SELF OFF AND WALK OFF.. I WOKE UP I WAS HAPPY I WASNT DEAD.. MY HEART HURT FOR A WHILE BUT I WAS OK NEVER AGAIN WAS I SCARED TO FALL IN MY SLEEP... MY FEAR WAS GONE, COOL..
What if when we sleep what we are doing is downloading our experiences of everyday life to the Creator to experience and interpret and upload and in a way for the spirit to experience what it means to be alive and every living thing is a part of this. Who knows these things other than the Creator of all...god bless you all and thank you
I think the reason the mouse was dreaming of the track backwards because he was made to run it several times and I assume he was never able to find his way back. So it probably thinks its sleeping deep in a hole somewhere and his brain was trying to figure a way out back to all the other mice! But who knows really.
My question would be. If seals evolved to be able to move one flipper to keep them a float and keep them from drowning, how did they keep from drowning before they evolved? The answer, They didn't evolve, God created them that way. As He did humans and earth and everything else.
This is just more Pseudo-Science Brainwashing!! Your dreams are one thing and one thing only. Your dreams are memories of your own experiences through the eons of lifetimes that your consciousness has been in existence. If you run into a person and then dream about them...it is because you have known them before. A lot of things trigger those different memories to come to life again in your dreams. If you keep a journal of your dreams instead of writing them off as random brain synapsis...you will gain great insight into the higher you...your soul.
Like I said for the most part other than the human brain there is no logical reason for sleep ten bucks says the comments I left nobody will truly know a good answer Theory and metaphor are not a substitute for replication of true fact provable fact and I'm not saying this in a harsh way I truly want to know because they 100% unequivocally said the brain does not have the ability to repair itself only do workarounds there is your Enigma there should be no logical reason why any creature really need sleep if there is no soul no consciousness so-to-speak don't confuse Consciousness with intellect or specialness okay we're talking very specific and that is your rabbit hole and many have tried and many have failed and still fail
If you really want to get into some cognate head games you need to look into how the human brain interprets the photons that we perceive the world and actually realize you're not witnessing the world in real time which they have done studies improved what is the mechanism that makes up for this time delay so you don't walk into a hole or off a cliff there is a mighty deep red hole right there because they have measured her real delay in real time and the mechanism that compensates to keep you safe
Yeah it is highly fascinating everything they're talking about really I'm not being a sniper but I would want to understand better the compression ratios in every living creature for storing memory vital memories and then in the human animal or we can recall early childhood memories to the point we understand the waking world around us vividly and quite a few people can remember way back that's a lot of data if you're dealing with a subject within 50 to 70 years or higher that do not have any problems with memory loss or cognitive abilities I want to know what the data ratio for compression is where it is really store because if you run a computer and you try to put 50 to 70 years worth of data that can be recalled well that's a mighty big hard drive
Yeah I can't buy into that you have essential system functions that are involuntary okay if you're learning that doesn't make sense then you would have major heart dysfunction not to mention a whole host of other things I just don't buy that the thermal is regulated by learned behavior maybe having too much blankets or too few or maybe the creatures did not whatever plume or the their winter coats or they didn't shed their coats those are more believable factors
And you cannot take a demographic from one geographic location and make it your template here in the United States we have a Melting Pot of different genetic pools and I'm sure it is not at the scale it is from that study overseas there's no way when you have that genetic diversity okay that study is no longer valid
Was the guy guilty obviously the parents did something or who knows maybe she was a child that did not like rules but quite often children do not run away unless there's some type of physical emotional or sexual abuse and being married to her she probably knew what she endured and could he have kept that in his mind and it bend the motivation to go and stab her parents or whatever the violent Act was yes cuz by Nature males feel the role or their duty is protector I don't think that jury totally got it right but was he really guilty well emotionally he was being a vigilante said he acted out during his dysfunction that's a slippery slope
Actually it is quite common if she was a runaway there was a reason she was runaway probably because the parents inflicted some emotional trauma and he carried that deep in his psyche so I wouldn't say he was out of the woods especially if he was a caring individual and it is the nature of a male to protect especially if that male is in love
With seizures I did mess up I have her grunting but I never heard anybody audible far as vocalizing or screaming so that I have to self correct I have heard the grunting but with Grand Mall or they do that weird lip-smacking
The mystery is why do any creature need real sleep is it the Decay rate would it be vastly accelerated or is it something truly unknown cuz if you think about it you drill down the only reason anybody would need down time is for regeneration but it is been said that brain does not regenerate it cannot be because of heet generation because we have systems that deal with that there's no real logical reason for sleep if you look at it from a scientific if physical machines were capable of regeneration they could run non-stop 24 hours a day other than cleaning there is no real reason for sleep unless you want to go to the consciousness but scientists don't like to go into that area do they there is no real good reason no matter how you tilt it tet the human body should need sleep at all because most of the human body is regenerative except for the brain which they Proclaim does not unequivocally the state of this for many decades so you have undeniable enigma there's no real reason for sleep if you want to treat the human body as if it was just a biological machine and other creatures 2 and the only thing that makes it significant or individual is the way the neurons fire differently in every human the synaptic connections because that's basically what's kind of being implied they're not going to talk about a soul or the consciousness or the Enigma of said items
Most of those boards that I listed are highly stackable and the processing power is increasing probably every 3 to 6 months maybe even faster I don't know why anybody would love their whole Lab out into the field not in this day and age
Maybe you should check out the new Computing equipment such as Arduino or they have so many flavors these days you can have it customized there are all kinds of board companies that will do custom designs and they can put it pretty darn small and it can be sent via Bluetooth internet even cell phone hell they got many ways to transmit and it is incredibly small where you don't have to take all that equipment only a laptop and your sensors and a pocket sized computer to run the sensors
I have a uncle that has grand mal seizures had it since he was a kid and I've never once seen him have a seizure where he was vocal I'm not saying it's out of the realm of possibility but this is definitely a new one on me and it doesn't explain another thing that I witnessed where people will have these weird tremors they do MRIS they come up clean no signs of Parkinson's and no lesions of any type and no signs of epilepsy you name it they've done it far is scans there is no type of drug or alcohol addiction which they should be the same anyway no designer drugs recreational whatever they call it I've witnessed many types of seizures but I can't say once that I actually witness one that had vocalization
And I've talked to many people that practice in this field and there are suspicions that people are having disorders due to environmental factors when a healthy adult is it it's nothing out of the abnormal their whole life and then all the sudden it comes out of nowhere I have witnessed this myself nothing detectable unless it's something new and unknown
They also use this method that he's talking about for self-driving cars from is unpredictable humans unpredictable wildlife there are million in one Center areas trying to pick where is going to be located in chaos is really turkey especially in physics I hear a lofty ideas that they say they can do it but they cannot replicate it without fail if they can replicate it at all
Because in the human mind you would have to have some math coprocessor compressing data in a efficient manner much what a hard drive on a computer you can't just switch out your memory loads or wherever you guys claim they are now because they switch it around quite a lot the real fun stuff the real interesting stuff is what happens with it Advanced MRI imaging now that is the thing to Magic
Here's the problem what do you think the compression rate for data is for the brain because let's see a 50 year old male who can recall earliest parts of childhood with perfect clarity and let's talk about dreams that reoccur that you've never been to have no known Psychopaths psychosis to the user or the patient places that they'd never been that place no trauma mentally or emotionally or stress I want to know what your compression rate would be for data in the human mind in The Limited area that you say memories are stored you can't give that answer just because you got some neurons firing off I'm primitive sensing devices does not mean much tell me your compression rate for data and why some people have perfect recall even right up to age 60 70 without any known psychosis just average lives even keel
its hard to explain.. but sometimes as I'm dozing off, I'll somewhat realize that my thoughts are starting to switch into "cruise control" and ill hear myself, and I'm explaining to myself a answer to a question that I guess ive unconsciously asked myself... but I notice that its like I'm becoming a "super smart person" just spewing really random but very DEEP knowledge.. lol I love when it happens
I feel their pain of the speakers as they were struggling to educate on something to which they themselves barely have any clue of or at least convinced of their studies at this moment. The mind and the brain are the 2 most complicated mechanics we have and I think unlocking the secrets in them would probably be unlocking the ultimate truth of us and our relationship to everything.
