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.
when I was young I could do anything in a dream, in my late 20s I had a illness that nearly killed me and left me with brain damage, now all I dream of is dead people and animals it may sound creepy but its not so bad and I can turn it off when its not wanted but I wish I could dream like I did when I was young. charl.. ps whats in it for the rat ? theres something not right sticking wires in a animals brains I'm sure you could find humans who can make a choice.
At night our consciousness is shut off to a degree where we are not awake but our souls can and do often leave our bodies and travel into the spirit world.
This is called astral travelling
Sometimes you remember where you go and sometimes you won't.
Other times our soul stays with the physical body and dreams .
Dreams are visual images and stories created by God and the angels In heaven as part of our karma on earth .
Dreams are put Into our consciousness through the third eye chakra .
The brain does not create dream images
I'm growing plants at my home and i grew up a plant in my dream mix with lemon and kiwi and after two days i saw on tv Dynamo did same thing, he took lemon and kiwi and mixed them together in 1 piece. how it is possible. is there any connection to my dream
they ask what will death be like? death will be just like your asleep, for when asleep, are you not awake..?? but if not then... when awake, should you give glory to in whole creation, for this is everyones present, all life partakes in this perfection for everyone who possess flesh may enjoy.. but atlas whom hath covenant richies in thy heaven, shall recieve thus ndmore for inwich hav you known thtruth, inwhich is why recognition
one may not necessarly in mind butsoul hath given recognition but one self lovedso thus hath meaning toperputuate tha cycle. for most common behaviors are such cycles. so unique yet key characters in such an interaction in whic best accomodate perfection in all congergation thus y which governs our physics is thus monikers whom may gamble apon tha manuevers of man in such this womb weve conceved from nd hav revelated from for thus we clean cut from the type of those whom bear offspring in the meadows yet were not marine. for we elope of all seasons yet deny the heat of womb. as we have no sport such thus every other creature is adorned. for all the benfits that may be taken in with our ability fr which we may consume for ease, understnding, fiend use abuse to infiltrate this system in which vacuum of ether we bask in.
This is very interesting, many of my dreams are about
Both my parents individually who have passed for many years
But in my dreams they are constant. And I never question
The fact that they have passed. They are just there
Like normal. We were a very close family when they
No JOKE.... Mel was my land lord in the mid- late 80's on Grand Ave/Lake St in South Minneapolis MN... he told us the story about him almost killing his wife in his sleep.....he said he was positive she was a wounded deer. He was the kindest man... he would bring us punk rockers donuts when he stopped by. What a sweetie :) peace
I woke up an I wanted a glass of milk so I went down stairs an no milk was in the fridge then next thing I know I’m waking up again an I was like okay it was a dream an I went to get some milk same thing happened again an then when I woke up again I knew I was reliving my dream over an over an I was getting kinda scared I’m not gonna wake up really then the last time I woke up an I went down an this time I saw my mom standing there an I saw something strange in the fridge an as I went to grab it I woke up an ran down stairs tripping an my mom was right there again but this time there was milk she had just got home an put in in the fridge an I was so relieved because I tasted it an it was cold an an good an I knew the dream was finally over. But it was so scary realizing I was waking up in a dream over an over. It happened only one other time but I forgot the dream just remember not being about to get out of the dream an it was faking me out over an over
We are spirits locked into a human experience. We contain the entire universe within our life-force, but like sleeping and being awake in the physical realm we are in, we are asleep to most of what we actually are. We could say that, just like countless thoughts, feeling, emotions etc, flicker in and out between our consciousness and our subconsciousness etc, many other 'selves' become apparent and non-apparent, as we are made up of many dimensions. If you have ever had a problem that you were not able to find solutions for until you were in dream mode and sorted it all out/found the answers etc, then that was you going to another 'self' dimension. We also experience many other realities of our deeper self this way. Just as it is in the physical world, Cause and Effect is also at work in the dreamworlds. Depending on our good or bad karma that we have created in our past or are creating in the present by our good and bad thoughts, words and actions, we will always experience that which we are worthy of.
HAS ANYONE EVER BEEN IN WAR ? I CANT SLEEP WHEN I DO I HAVE VERY BAD DREAMS I HAVE TALKED WITH DR NO ONE CAN HELP AND I ONLY TALK 2 MY ARMY FRIENDS ABOUT NOT THE WAR WE WERE THERE AND ALL HAD A BAD 13 MTHS I DONT KNOW WHAT TO DO DOES ANYONE FEEL LIKE ME WHAT DO YOU DO ITS GETTING HARD FOR ME
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
