  • Terror, hallucinations, paranoia, psychosis.

  • The effects of sleep deprivation aren't just devastating, they can last for life- but just

  • how long can you survive without sleep?

  • T+ 24 Hours With No Sleep

  • You're drowsy, but that's nothing new.

  • Most people have gone a full day without sleep several times in their life, and you're no

  • exception.

  • You know you're prone to becoming irritable with people the longer you go without sleep,

  • so you do your best to stay away from others.

  • You immediately close your Facebook and Twitter tab, because you definitely don't have the

  • patience to argue with your uncle who still thinks Coronavirus is a hoax.

  • Not if you don't want next Thanksgiving to be a complete disaster.

  • You're trying to catch up on school work, but you're finding even simple questions difficult

  • to answer.

  • It's definitely taking you longer than it should to answer which Union army general

  • went on to become President after the Civil War- you keep reading the question to yourself

  • trying to make sense of it.

  • Worse yet, you know that you just reviewed this material a day ago, but you're having

  • a lot of trouble with your short term memory.

  • T+30 Hours With No Sleep

  • You gave up on school work, it's impossible to concentrate right now.

  • You sit down to watch some tv and are shocked to discover an entire hour's gone by in what

  • seems like just a few minutes.

  • On the flip side, that Postmates you ordered that was supposed to take 25 minutes to get

  • here is taking an eternity- but when you check the app only ten minutes have passed.

  • This is making you even more irritable, and you're snapping at friends and family over

  • the slightest provocation.

  • Sleep may not come, but that doesn't mean life doesn't go on.

  • You've gotta drive yourself to work and you're terrified to realize that you've driven entire

  • stretches of road and have no memory of it.

  • Were you asleep, or is it just more short-term memory problems?

  • The fact that you don't know is terrifying, and you are extremely relieved when you finally

  • pull up to work.

  • You have no idea how you're getting through the next eight hours, your back and shoulders

  • are aching something fierce and when you hold your hand out in front of you it's shaking

  • noticeably.

  • T+36 hours With No Sleep

  • You had to leave work early.

  • It was either that or tear off a customer's head.

  • Concentrating on people's orders was almost impossible, requiring every ounce of willpower

  • you had just to get a simple order right.

  • It didn't help that every single entitled customer likes to treat fast food employees

  • like they're human trash, when they're just trying to earn an honest living.

  • The thought makes you absolutely furious- which is why your manager told you to clock

  • out.

  • Are you fired?

  • You have no idea, you didn't even bother asking.

  • Honestly, you don't even care.

  • Because you don't care about much right now.

  • By some miracle you manage to drive home without wrecking, but again you're alarmed at just

  • how little of the trip home you actually remember.

  • You hope it's just your ever-worsening short-term memory, and not because you fell asleep behind

  • the wheel.

  • You should eat, but you're not really hungry anymore.

  • You're just.. tired, but amidst the exhaustion you suddenly get a small jolt of energy.

  • That's your body pumping sugar reserves into your system to boost your abilities temporarily.

  • At this point, even your body has started to realize that something is seriously wrong-

  • it's switching to fight or flight mode believing you're in a life-threatening situation preventing

  • you from sleeping.

  • T+42 Hours With No Sleep

  • The short-lived energy boost is gone.

  • All that's left is a sense of apathy.

  • It's becoming difficult to concentrate on.. anything, even your favorite shows.

  • Everyone in your house is giving you a very wide berth, because you're not just irritable

  • anymore, you're downright obtusely stubborn.

  • Things are definitely your way, or the highway, as your ability to cooperate and reason with

  • people all but diminishes.

  • Your lack of sleep is effectively shutting down your ability to conduct higher brain

  • functions, and you're reverting to a more base, primitive state.

  • If you can't sleep, you can at least boost your energy- you need some Red Bull.

  • It doesn't matter that the store is several blocks away, or that you almost crashed your

  • car a dozen times on the way home, you need that Red Bull and you need it now.

  • It takes you a few attempts to get the key into the ignition, your hand-eye coordination

  • is seriously off, but soon the car's revving to life and you're off to the store.

  • Luckily it's all residential roads to the store, and traffic is extremely light.

  • For a moment you panic thinking about a kid's ball bouncing out into the street, and the

  • unaware kid rushing out after it right in front of you.

  • You try and be hyperalert, and replay the imaginary incident over and over in your mind

  • until finally, in your mental fog, you suddenly aren't sure if you were imagining it or if

  • it really happened and you just don't remember it.

  • In a blind panic you pull the car over and rush outside to inspect the front of the car-

  • and a wave of relief washes over you as you realize that there's no dents.

  • It was just in your head.

  • As you drive back home from the store though you swear that you're starting to see that

  • kid and his ball playing in the yards of the homes you're passing by.

  • It doesn't matter that physically speaking, this same child couldn't possibly be in different

  • yards at the same time, it doesn't matter that none of this makes any sense- to your

  • sleep-starved brain, this kid and his ball are as real as the car in front of you.

  • Oh crap, there's a car in front of you!

  • You don't even realize that the other car has hit its breaks until you smash right into

  • the back of it.

  • In a blind panic, you put your car into reverse and speed off!

  • Wait, what?

  • Did you just flee the site of an accident?

  • Why didn't you just exchange insurance information?

  • What in the world are you even doing?!

  • None of this helps, and instead just makes you more panicked and paranoid.

  • You gotta get home, and you gotta get home fast.

  • And you gotta hide the car...

  • T+48 Hours With No Sleep

  • You just dozed off.

  • You wake with a startled jump- what just happened?

  • You were trying to do the dishes and just sort of dozed off.

  • That's when the pain hits you- you left your hand in the running hot water.

  • But, if you're honest, it doesn't even hurt that much.

  • Just like your other senses, even your ability to feel pain has dulled.

  • From the sink you can see out the kitchen window and into the driveway, where you hastily

  • parked and threw a tarp over your car.

  • Why did you do that?

  • Oh, that's right.

  • You hit a kid on the way home.

  • Huh- no!

  • You got into a fender bender.

  • Wait, why did you run away from a fender bender?!

  • It doesn't matter.

  • Well, it does, but your brain can't process the consequences right now.

  • Your family is gone, took off for the weekend and decided you and your bad attitude could

  • use the time alone.

  • Where did they go though...?

  • Try as you might you can't quite remember.

  • Oh well, it doesn't matter.

  • Might as well see what's on the................. (long period of silence)...........

  • huh?

  • Oh crap, you fell asleep again.

  • These micro sleeps are lasting 30 seconds to a minute, and are totally out of your control.

  • Your brain is literally hijacking control away from you in a desperate bid to save itself.

  • You're more of a passenger than the conductor right now.

  • T+ 60 Hours With No Sleep

  • You don't know this, but inside your body an infection is taking hold.

  • Luckily it's just the common cold, but the immune system cells responsible for destroying

  • foreign invaders are not reacting as quickly as they should be.

  • It's like every function of your body is experiencing the same sluggishness and confusion that you

  • are, leaving your immune system greatly compromised.

  • You're hearing things.

  • Sometimes you'll hear snippets of conversation that you remember from long ago, and for just

  • a moment you believe you're back in that time and place.

  • Only to turn around and instead of seeing the speaker standing there, there's... nothing.

  • You're hearing ghosts created by your own, slowly degenerating brain.

  • The barriers between memory and the present are getting muddled.

  • You're also starting to sense presences that are clearly not there.

  • You've heard ghost stories before, and people speaking about being able to sense the dead

  • in the room with them, despite not being able to see anything.

  • It's a lot like that, and you can swear that there's people in the room with you, even

  • whirling around expecting to catch them standing right behind you.

  • But there's no one, it's all in your sleep-starved mind.

  • Your brain is starting to lose its ironclad grip on reality, misinterpreting sensory data

  • and sometimes creating completely false data of its own.

  • You are turning into a very badly glitching computer.

  • T+ 72 Hours With No Sleep

  • You have an unbearable urge to sleep, and yet for some reason are unable to.

  • At this point you know most people cannot prevent themselves from sleeping anymore as

  • the brain literally shuts down.

  • For some reason though, your brain refuses to allow you sleep.

  • Your mood is impossible, and you're glad that nobody is around.

  • The slightest provocation will set you off, even if the only other humans to interact

  • with are the ones on the TV.

  • It doesn't matter, because even their offenses are as real to you as if they were physically

  • in the room with you.

  • You try to take a break and play some video games, but your hand-eye coordination is all

  • but completely lost.

  • You're hungry, but not nearly as hungry as you should be, and you find that you're rarely

  • eating.

  • T+96 Hours With No Sleep

  • You don't quite recall the last time you used the bathroom.

  • You don't really know when's the last time you ate.

  • Maybe a day ago?

  • It doesn't matter, you're not that hungry.

  • Or thirsty really, despite your dry, cracked lips.

  • You're dehydrating, and soon you'll begin starving, but you honestly don't care.

  • You don't even feel like you need to eat anymore.

  • Besides, if you need a meal you can just ask your mom to make it for you.

  • She's standing right there in the kitchen, leaning against the closet door.

  • She's been standing there for hours, but when she doesn't answer your questions and you

  • go to ask her why, you realize you've been staring at a broom the entire time.

  • There's something funny about that, and you giggle.

  • Normally experiencing such a dramatic hallucination would be alarming, but honestly, you just

  • don't care anymore.

  • T+168 Hours With No Sleep

  • How long was your family saying they'd be gone for?

  • Just the weekend, right?

  • Sure seems like they've been gone a long time.

  • You have no idea how many days have passed, but you're pretty sure it's been more than

  • three.

  • You're fully in the grip of sleep deprivation psychosis at this point, and your hallucinations

  • are just as real as the physical world.

  • They don't always make sense, and they don't always materialize in dramatic fashion- sometimes

  • it's just strange sounds you hear.

  • More often it's you confusing household objects for people, like the old coat and hat on a

  • coat rack trick from cartoons.

  • Your sense of smell seems to be.. off as well.

  • The garbage has been stacking up for a while now- you totally forgot which day was garbage

  • day- but it's almost like your nose chooses to focus on only specific scents and ignore

  • the rest.

  • It's not all that bad really, you can smell the citrus smell of oranges coming from the

  • garbage, while blocking out the smells from all the rotting food.

  • You don't even realize that the house absolutely stinks now.

  • Or you, you haven't showered in weeks.

  • Or is it days?

  • You're not sure, you're just sort of... confused all the time.

  • T+264 Hours With No Sleep

  • You just realized why your family's weekend getaway is taking so long- you don't live

  • at home anymore.

  • In fact, you live alone, without roommates.

  • Which is a good thing, because both you and the house are in horrible disrepair.

  • Also, you're pretty sure you're fired from your job.

  • You're not really awake, but definitely not asleep- you exist in a sort of twilight state.

  • Normally it would alarm you to realize that you basically invented a false reality of

  • still living at home with your parents, but you aren't nearly aware enough to care.

  • At least you're eating, but only because you have to.

  • Thank God for postmates, because the thought of cooking is overwhelming to the point of

  • being painful.

  • Your confusion is so intense, you find yourself stopping in the middle of tasks with no memory

  • of starting them- or why.

  • The hallucinations have become so frequent you've basically learned to simply ignore

  • them.

  • They're mostly auditory, with past conversations replaying so vividly you could swear they

  • were happening right now, and random tones and sounds that make no sense but are completely

  • real to you.

  • You're well past the stage of microsleeps, you're drifting into moments that can at best

  • be described as 'wakeful sleepness'.

  • Your body and mind are definitely awake, and you just sort of drift into nothingness as

  • you stare blankly ahead of you, but it's not the sleep your brain so desperately needs.

  • You don't know how long you can keep this up, and honestly, neither does science.

  • You've officially reached the world record for sleep deprivation, and every hour ahead

  • of you is uncharted territory.

  • What is known from animal experimentation is that sleep deprivation will without a doubt,

  • eventually kill you.

  • Brain functions break down to a degree that organs begin shutting down.

  • Just like a faulty computer network, the brain gets increasingly glitchy, until finally,

  • it simply can't command the organs to continue life-preserving functions.

  • How long until you simply shut down and die?

  • Nobody knows for sure, but to your confused mind it doesn't really matter.

  • Now go watch human sleep experiment that went horribly wrong, or click this other video

  • instead!

Terror, hallucinations, paranoia, psychosis.
