How do you know you’re not dreaming? - Daniel Gregory

--

Bizarre things happen in dreams: you fly, or conjure an all-you-can-eat buffet out of thin air, or get chased by witches through the halls of your school. But the strange things that happen in dreams don’t seem strange at the time. So, how do you know you’re not in a dream right now? Is there a way to prove that you're awake? Daniel Gregory digs into the philosophical theories of wakefulness.

Becasue usually when i dream my life is actually happy.

[Shuang_Shuang]

As a kid, I once had a dream within a dream within a dream. It really confused me every time I woke up because each dream was hyper realistic, I was just in my room, so I was 100 % sure I was awake after each dream

I like the surreal images of this video, very appropriate.

The good news is that it actually doesn't matter whether this reality is actually real or not, because we wouldn't know the difference anyways.

So let's enjoy this dream and see y'all on the flipside!

I actually had a physical condition that led my body to starvation and one of the most terrible things was I couldn't tell if I was awake or dreaming. I had very vivid dreams and couldn't tell them apart. When I finally knew that my body was starving I watched videos from survivalist and people that survived a long time without eating (jungle, ocean etc.) and it all made sense

“From the moment I fell down that rabbit hole I've been told where I must go and who I must be. I've been shrunk, stretched, scratched, and stuffed into a teapot. I've been accused of being Alice and of not being Alice but this is my dream. I'll decide where it goes from here.”

[KaliTakumi]

One of the longest lucid dreams I had started with me waking up in my bed. I only knew it was a dream because I got out of bed and had shoes on. And only at that point did I realise I was in a bedroom I didn't recognise lol

[huahualipo]

"Is it me dreaming about a butterfly, or a butterfly dreaming about being me?" Zhuang zi the philosopher has a poetic way of expressing it, thus forever linked butterflies to dreams and reality in Chinese culture ever since.

[teruphoto]

I ask myself how I arrived at the current moment and remember things that have happened since I woke up.
I do this so regularly that I often ask the same questions when I dream, which leads to lucid dreaming.

[shadp]

The scenario goes like this: "Aight, imma bout to sleep now so I'll try being aware in my dream"

And then proceed to dream but not question the absurdities happening. It's like the dream doesn't allow you to be aware. And then in the morning, regret happens and you'll say something like "Damn, why did I not realize that that was just a dream?"

[Nikhil-iqvm]

As a kid whenever I had a lucid dream I always ran around in the dream for some reason, I didn't know why back then, but it always worked in helping me wake up. Even now I always want to wake up the second I realize that I'm dreaming...

[vadsgator]

Philosophers are just dreaming about how they're currently in a dream within a dream

[riddhimadey]

Ted ed is such a brilliant and educational platform, never fails to inspire and ignite the spark for learning in me!!
Also, I've a request on that note- Cain's Jawbone seems to be a really mind boggling, intriguing and a fun murder mystery for most of us booknerds and bibliophiles out there! Not the solution to it, but maybe a video on how the developement came about, Edward Mathers' mastery and some sort of analysis on it would be really interesting! Thank You!

Who doesn't experience very realistic dreams every once in a while? Even when they are less realistic I still feel the emotions, and at that moment I believe what happens

[saschaberger]

I learned to use reality triggers in my dreams to induce lucid dreaming. My main one is looking at the back of my hand and then start counting the fingers. I did that in random intervals everywhere I went for about two weeks, then I started to do that automatically in my dreams. As soon as I see my backhand in a dream I instantly know it a dream and yeah that changed my dreaming forever. By now I know for sure that I'm awake because I can't fly my own in real

[smolcat]

as a lucid dreamer, the most special dream i had was meeting my late grandfather in his home, as if meeting him in real life. i didn’t get to say goodbye to him when he passed. i remember telling myself in the dream “i know he’s passed in real life, so this is a dream”. i hung out with him, talked and though i don’t remember the conversation, i felt closure because i did all the things i would have done if he were still alive today, in that dream :)

[graceh]

I’m a lucid dreamer, and it’s always been fun in dreams to think of something and making it happen whenever I want and how I want it. I can also extend the dream if I feel like it’s going to end, or— if I’m in an uncomfortable dream—wake myself up.

Waking life seems like a dream (or nightmare usually) most of the time so I wouldn't be surprised at all if, one day, I eventually find out my waking life was a dream. If that's the case though I need to wake up cause this dream is horrible.

[DasGreenCow]

Like descartes said in the video. Like a movie edited well. In dreams we travel from location to location and event to event to conversation to event instantly. The existence of boredom and actually doing the in between bits proves we aren't asleep.

I once fell in my dream and i felt so real....I even talk in my dream and when I woke up I kinda think that I already had this even asked my mom after waking up that did I talk to you about this thing??...😂😂I even have my sister some insta profile growing idea in dream and asked my sister that if I told you anything or not but she said you just woke you-
