    During my time at university studying pure mathematics I had an interesting experience of doing a challenging sheet of combinatorics problems during a vacation. Every day I attempted one question and got stuck on it. Then the next morning I woke up knowing the solution. It was a recurring thing: this happened every day for about 2 weeks until I had solved all the problems.

    For me this a big eye opener about the importance of sleep and relaxed thinking to solve challenging problems.

      Yeah, when you are stuck, put away that red bull and step away from the keyboard, kids.

        This might be why agentic development/vibe coding leads to more burn out. It's been a long time since I've truly been 'stuck' on a problem and needed to sleep on it to figure out the answer. Now I just ask Claude to fix it until it's fixed...

    Aside, but I struggled a long time with regular sleep. I have been a night owl since I was a kid. I experience late hours as magical, don’t know how to describe it. So I always slept too little, then not at all, then drifting and sleeping in.

    But I somehow managed to have a regular schedule and now I start to sleep at 00:00-01:00 very often, sometimes even earlier.

    No idea how I managed to do that. I guess I just did improve many small things, like getting rid of bad habits, being more content, appreciating sleep more, prioritizing things differently.

    I wish everyone good, healthy sleep.

    AI does the work during the day and we learn while sleeping. Society doesn't collapse from ignorance. We have a new movie plot gentlemen.

    So I guess having dreams about recurring meetings is... honing corporate skills?

      It also counts as overtime, right?

      Is the main theme that you suddenly realize you aren't wearing pants?

      And if so, would you say it has improved your pants wearing performance on the job?

    While you're sleeping I'm practicing my skills. Enjoy being poor, suckers!

    Lucid dreaming is a cool concept but I've never been able to pull it off. I still try, though!

      It sort of just happened to me a few years ago. It’s neat—flying is fun. (As is the opposite, when it just doesn’t work and I wake up sort of laughing at myself for having spent, presumably, hours jumping around in my dream.)

      But at least for me, the price was dreams, the moment I go lucid, ceasing to be self directed. I get that I’m in a movie, and I have to always create the next step. Nothing surprises or horrifies anymore. (If I’m lucid.) I have to kind of create my own magic, which isn’t particularly restful.

        Yep, same. The dream gets incredibly boring after you get control of it.

          but but, you can do whatever you want?

      Keep a dream journal. There any many methods for achieving it but if you keep a dream journal long enough you'll start getting consistent lucid dreams.

      My tell is to recognize any room with a piano in it. I naturally want to sit down and play this piano, but the keys are totally wrong. No problem, I'll look around and, lo and behold, dozens more pianos all... with the keys in the wrong places. I can't play anything. "Oh, this again. I must be dreaming. How frustrating."

        A very regularly occuring dream is that I'm in a train and realize that I don't have a ticket (never happened IRL), so I want to buy an e-ticket, but the ticketing app does not work. The text changes all the time, the buttons move around, weird errors, and then I realize 'yep I'm in a dream again'.

        The nicer lucid dreams are those were you can fly or make spectacular light and colors, but I find that it's usually a difficult balance to avoid waking up.

      I was really into it in my early 20's. One way to tell if you are mentally in the state to lucid dream is if you no longer feel tired. One night, after a grueling hike, I was completely exhausted when I went to bed. I closed my eyes, and moments later all my exhaustion just vanished, and I began to explore the space.
      • galleywest200 27 minutes ago
        Another way is to try to see what the clock faces say in your dream. Also, see if the light switches behave as you would expect.

    Two months ago my partner recorded me speaking in my sleep. I was speaking fluent Mandarin. I always thought sleep time is used for learning (among healing etc), but now I am convinced.
    • detribaby 53 minutes ago
      Well you’ll have to give us more. Do you speak Mandarin at all?
      • tsukurimashou 16 minutes ago
        spoiler, he is Chinese and only speaks Mandarin
      • consumer451 36 minutes ago
        And, what was the partner's ability to benchmark? What is their level of familiarity with the language?

        I would love to believe.

        • jtbayly 19 minutes ago
          It was a recording. I dare you to ask for it.

    Have anybody managed to use sleep to learn language? How ?

      I have dyslexia and in high school learning my lines for plays was really hard but I loved doing plays, so I recorded myself saying my lines on tape (yah, I'm old) and used double cassette to fill 2 tapes with them, then run them over night while I was sleeping. I've never used this in my adult life but it worked pretty well for my lines and I suppose maybe you could use it to learn a language?

      Edit: Claude tells me I was a head of my time, apparently it works but not net new, you have to also be working on it awake, it's called 'targeted memory reactivation (TMR)": https://pmc.ncbi.nlm.nih.gov/articles/PMC12592824/

      While I think it's a compelling idea that playing speech in your target language while you sleep can help, I don't think it's ever been demonstrated to work.

      Having said that, that sleep is incredibly important for learning anything! I practice my language learning during the day, a little bit every day, and I prioritize getting good sleep. This is mostly just trying to go to bed at the same time every night, avoiding alcohol, and giving myself an hour before bed with low lights to read and calm my mind. When you sleep, memories are consolidated, organized, and tagged for long-term storage. I will sometimes wake up in the middle of the night and bouncing around in my mind are echos of phrases and words from my target language. I figure it's working.

    Edison, famously, solved problems in a light dream state [1].

      Interestingly this is not something native to Tibetan Buddhists. Neoplatonists had something similar, and even Orthodox Christian monks speak about literally "praying ceaselessly" which inludes prayer during sleep, it's definitely all lucid dreaming

    > In perhaps the most striking example of learning during sleep, Konkoly, Paller, and several collaborators witnessed what amounted to conversations with people who were in the midst of dreams. Independent lab groups in the U.S., France, Germany, and the Netherlands asked lucid dreamers to answer yes-or-no questions and solve simple math problems. Electrodes measuring body and brain activity verified that the participants were not awake. Martin Dresler, a sleep researcher at the Donders Institute, who ran the Dutch experiments, said that they were able to verbally deliver new information to the sleeping mind—and to receive responses. Some people could remember the questions they had been asked when they woke up. “This is a form of very complex learning,” he told me.

    My wife used to think that I had terrible sleep apnea because I'd repeatedly quit breathing for a minute or two at a time and then gasp for air, but it turned out I was just dreaming about freediving for lobsters.

    It's gonna be really sad in 10-15 years when all the sc bros are hustling and grindsetting their dreams away.

    Now there is no excuse anymore to be working less than 24 hours a day.

    tl:dr "Andrillon warned against trying to harness the sleeping mind in the service of the waking world." https://www.nature.com/articles/s41539-024-00276-0

      Proper sleep definitely isn't optional.
  • metalman 1 hour ago
    There is no such thing as "should". The thing is possible, therefore humans will do it. The only question is, who is we?
    • azan_ 1 hour ago
      Well, you shouldn't smoke yet people do it. I think the article posits question whether we should in similar spirit.

    After two weeks I woke up and didn't notice it was German tv. Eventually after 5 minutes an unknown word came along. I still can't speak it.

    When 13 i use to code till 1-2 am. In school I slept with my eyes open till 11. The information was stored and organized but I was unaware of it. I remember tests where all of the questions talked about topics I never spend a conscious thought on. But I knew all the answers. Quite the surreal experience.

    Teachers sometimes wondered if I was still in the room or they just asked questions. My mind would grep the most recent chunk of speech, parse it and respond as if nothing unusual was going on. The mind raced but I talked slowly to portray the slight delay more natural.

    I learned you don't want other people's bullshit in your head. It needs to be questioned first.
