Sleep

When you sleep you actually wake up

>>8990346
you don't need sleep. sleepiness is just Jews taking your life-force away for shekels to be made.

The interesting thing about sleep is that anyone can do it. You don't even need training or suchlike. Neuroscientists suppose that it's some sort of mechanism embedded into our brains from birth, because the data shows nobody has forgotten how to sleep so far.

>>8990366
sometimes I feel like I'm really bad at it and it sucks :(

>>8990366
That prion disease found a way to fuck with sleep.

>>8990346
Sleeping less correlates with intelligence. Einstein slept for 3 hours a year. I made both of those things up.

>>8990346
Sleep is for slackers. Take drugs and coffee to increase your productivity.

>>8990346
its a nice thing to get some rests
try it sometime? :)

It's for the weak.

When you're dreaming, you believe your dream is real and you have little memories of your waking life.

When you're awake, you believe your waking life is real and have little memories of dreams.

Now I know you're all awake right now so you assume your waking life is real, but when you're asleep you'll assume your dream is real.
They're both contradictory beliefs that you have every single day/night. How can you be certain which is true?
Is there any scientific proof to support either belief?

>>8990346
>sleep

Its really simple OP, if you feel or think you need more or less of it, you probably do and I think its highly variable how much is optimal although most people seem to fit somewhere between 5-10 hours per 24 cycle

>>8993044
There are a lot of problems like this where we can't truly prove one side, but it's still visibly apparent that one is correct and the other is not

Within dreams there is never a consistent concept called "science" that allows us to scan brains and analyze what's happening to them while people sleep

Within dreams there isn't a consistent concept called "the laws of physics" which are ALWAYS followed without error

Within dreams there isn't a consistent flow of time between the {dream, non-dream} transitions. They pick up randomly and drop off randomly.

For this reason we should heuristically assume dreams are the fake half. For the same reason we don't go around legitimately believing the zombie hypothesis, etc.

I am personally a huge fan of sleep but that is probably because I am so good at it. I don't suffer from meme conditions like sleep apnea and I create the perfect environment for myself (cold room, weighted blanket, white noise from air conditioner and rainymood). Needless to say, I sleep like a fucking log. Usually a solid 7-9 hours every night.

I don't know if it has provided me with any benefits. It did however make me super sensitive to sleep deprivation so I pretty much start to experience something similar to methamphetamine induced psychosis after staying up for a single night.

No joke

>>8990346
It's bullshit the Jews pushed on us

>>8993088
I feel most awake going to bed, and waking up I feel like shit. When I wake up, I feel like how people say they feel after a long day at work. This feeling can last for quite some time, and I'm never really *awake* until late at night.

It's fucking bullshit and destroying my quality of life.

>>8993044
Get back in your drug coffin, Kirkbride.

Its a jew trick dont fall for it

During sleep your glymphatic system fills with cerebrospinal fluid, cleansing your brain of waste products.

>>8990764
Fuck that shit scares me so much

>>8993044
lucid dreaming shows that that is bullshit
I keep a dream journal myself, and the more I dedicate myself to keeping records of my dreams the more I recall.

>>8990364

why do humans get pleasure from sleeping?

>>8990346
More importantly will we ever find a way to not have to sleep or reduce it?
Such a waste of time.

>>8990346

>Redpill me on sleep, /sci/

Sleep in a completely dark and quiet room. Even a small amount of light or sound can cause insomnia. The body notices it. It is the first thing to try before blaming "work stress" or medicating.

>>8993088
>>8993132
Sleeping too much can make you tired

Optimal sleeping hours depend on the individual and are usually between 4-8 hours

Sleeping 8 hours+ every now and then does not harm you

>>8993427
IMPEACH DRUMPF!!!

Engineering students have no clue what sleep is.

Is there any theory on what makes us dream? I want to dream ore.

>>8993266
Lucid dreaming = remembering your waking life in a dream
Dream recall = remembering your dreams in waking life

In this regard, lucid dreaming and dream recall are complete opposites.

>>8993431
>Sleeping too much
>adults average 4-8 hours normally

What did I do wrong exactly?

>>8993044
I don't dream much. There's the truth.
And my dreams are different almost every time

>>8993088
You basically explained it yourself. Combination of young age (you might be a late bloomer and teenagers and young adults need more sleep for development, 9 hours is typical), malnutrition and physical exhaustion (work + working out).
You're not a robot like capitalism wish you to be. You compare yourself with some idea of perfection you assume is "normal", and you're surprised why it doesn't work.

I'm a neet and I have absolutely no trouble with sleep. 10 to 12 hours is all that I need.

REM sleep is all about fear extinction and is integral in making conditioning work. Other sleep is needed so you produce release gh which heals micro injuries and makes you absorb nutrients.

Also the reason our bodies paralyze itself while we sleep is that dreams are essentially our brains producing the same electrical pattern as an experience while we were awake, but with very very slight variation. Combine this with the principal of synaptic plasticity and it all makes sense, we train our brains on any situation dealing with, say, touching fire, hundreds of times so we know to be afraid of fire, but only in certain events.

>>8993861
>>8993849
what is fear extinction?
why can't nutrients be absorbed and micro injuries healed without sleep?

>>8993861
Going a little further (I woke up only two minutes ago, hence why this is a little jumbled, but I did some research on sleep during my undergrad days when I was getting a degree in neuroscience):

>>8993864
Purging unnecessary fears. Conditioning goes away after a certain amount of time, which is called "extinction". If every time you ate I rang a bell, you'd start to associate the sound of a bell ringing with food, but if I stopped, it would no longer be useful for you to associate those two things together so it would go away. Fear extinction is this concept plus the concept of removing generalized fears, making them more applicable to specific situations. There is also a study (can't remember if I linked it), that showed that the amygdala (which in laymans terms is the "fear part of the brain") had significantly greater activation in response to increasingly "frightening" visual stimuli in people who hadn't gotten sleep in 24 hours vs those who had. This kinda shows what I'm saying.

As for nutrients question:

Given that we share these more "primitive" forms of sleep with lizards and other animals (but not rem sleep, lizards don't dream), I'd say its so you don't exhibit this behavior when you're in a situation that you could get into a fight over. Sleeping takes energy, and generally "should" happen after you've digested food (so that nutrients are present), so it makes sense that it would be associated with immobility so you could find a nice cave to get protected in and sleep, and just focus on healing.

>>8993876
so if a person sleeps alot more it means they feel more fear than other people and their brain has to reduce that more?

>>8993885
I wouldn't say that. Their body could just be less efficient at the sleep process, or a million other factors.

>>8993666
they suck cock all night long

>>8993261
the most you can do is not eat human meat

>>8990804
First part is true but correlation is not causation. People who perform more 'evolutionarily novel' activities tend to sleep less. Only because those activities themselves infringe on the sleep schedule.

>>8993849
No wonder I'm afraid of everything.

>>8993876

den how cumz i can fly and fuck sarclet johanisun in my lucid dreams but not in my lucid wakes

>>8996439
Because your lucid wakes aren't your own

>>8996439
Lucid wakes implies you have free will to control your life.

Maybe dreams are the only time we have free will and when you're awake everything is pre-deterministic.

you can actually stack sleep hours for big awake time

i.e. sleep for an entire weeks worth of rem in one sitting and you can stay awake for a month straight.

>>8996912
this can't be true

>>8996912
This is blatantly untrue.

>>8993969
I guess that means no hot dogs then huh?

>Sleeping too much can make you tired
I've read that you are supposed to sleep as much as your body wants to, which is how humans have been doing for thousands of years.

Why do dreams feel more real than reality. In the sense that when you have a scary dream you are more scared than you've ever been in your life before.
I'm sure you've had dreams before that felt like more than an experience and memory.

Redpill me on ECT and waking up remebering nothing.

>>9002062
There is no introspection during dreaming, so their is nothing to contradict the experience as it is happening and you are living externally and in the moment.

>>9002087
This sounds like a drug desciption.

>>9002094
I just know in your waking life you have your subconscious, so wherever you experience something, you can look inward and reflect on what is happening. That experience never exists in your dreams. Your whole brain must not be active at the time.
