This trope is about torture, bullying, punishment or abuse with Sleep Deprivation.
Sleep deprivation, also known as insufficient sleep, happens if an individual gets less sleep than they need to feel rested, awake and alert. Not having enough sleep like when you're busy and must pull an all-nighter, or if you're so stressed that you can't fall asleep, or if you're disturbed by those noisy kids next door — that is bad enough. Now forcing someone to be awake and deprive them of their basic need is just plain evil and cruel. In Fictionland, sleep deprivation is often used as a way of bullying, punishing, abusing or torturing our poor characters.
Insufficient sleep has many bad effects on the body. It can cause loss of concentration, confusion, lapses or loss of memory, aching muscles, headaches, hallucinations, seizures... up to the complete exhaustion and failure of the organism, by which we mean death.note Sleep deprivation can be used to disorientate abuse victims and set them up to have more power and control over them.
Sleep deprivation can be used as a means of interrogation. Though it is generally agreed that the suffering is not as bad as other forms of torture, because the word "torture" implies that the pain is more intense and the cruelty more off the scale. However, it is still considered inhuman and degrading, especially if used non-stop or for prolonged periods of time. In fiction, it's considered a "clean" and "effective" method of torture. Often used by Secret Police or Police State on their citizens or by military personnel interrogating captured soldiers from enemy sides. The trope is likely to occur in Spy Drama with spies, secret agents, double agents, or some other form of espionage professional. See also Enhanced Interrogation Techniques.
Members of special forces and soldiers might undergo so-called "resistance interrogation" programme, a type of military training that prepares them to resist interrogation techniques such as sleep deprivation after getting captured by the enemy. Usually they experience sleep deprivation during the training so that they might understand the effects of lack of sleep and they are also taught how to deal with the situation.
Compare/contrast to The Insomniac (characters who can't sleep or have trouble falling asleep) and The Sleepless (characters who don't need to sleep). See also The Ludovico Technique, which often involves sleep deprivation and is usually portrayed as torture.
Sleep-deprived, tortured examples:

L refuses to cave even when he's on the verge of blacking out and eventually gets Rae to stop depriving him of sleep by pointing out that if he perishes from lack of sleep, it won't be a 'real' victory for Rae who wants to prove that he can corrupt even the most unwaveringly moral of humans like L.
- Foreign Correspondent: The conspirators torture Ambassador Van Meers for information, using bright lights and loud jazz music to keep him awake for days on end.

And he has toadies among the crew who are ready to tell him if Hether ever fails in his task.
- In Professor Dowell's Head by Alexander Belyaev, Dr. Kern tries to drive Arthur Dowell (the title character's son) insane by trapping him in a room with permanent lights on and playing loud annoying music — essentially, by depriving him of sleep for many days. Unfortunately for him, Arthur's willpower is strong enough to first pretend to sleep peacefully, just to spite his captor, and then to actually fall into a kind of restive half-sleep state, thus surviving the torture.
- The Scarlet Pimpernel: Sir Percy withstands 17 days' worth of torture with sleep deprivation in Eldorado when the French authorities are trying to break him.

- Frasier: Late in the series, Marty gets a job as a night-shift guard. One episode has a B-plot where his boss punishes him for not dating the guy's sister by making him work ungodly hours. It gets to the point that Marty is easily confused and disorientated just being up and around in daylight, much to Frasier's concern.

Frasier: What, you don't like the sun?
Marty: Us night-shift guys call it "the Scare Ball".
- Homeland has an interrogation scene with a prisoner who has been deprived of sleep from sporadic Death Metal blasts.
- Horatio Hornblower:

When Archie gets a fit, implied to be stress-induced by Simpson's presence, he orders Clayton to take over his "duty". All the more cruel since Kennedy, Clayton and Hornblower are friends.
- In "Mutiny", the crew has to deal with a crazy captain. Hornblower is punished by having to serve 36 hours of continuous watch (that later gets even prolonged). Buckland later says that continuous watch is as good as a death sentence.
Sawyer: Were you still a midshipman, I would flog you like we have Mr. Wellard. Your position, however, dictates a more imaginative approach. You are on continuous watch for the next 36 hours and I would remind you that an officer caught sleeping on duty is subject to the most rigorous penalty of the Articles of War. And you know what that is.Hornblower: Yes, sir.Sawyer: Then God help you if you're found asleep.

- Witch trials. One method of extracting confessions from victims, used in England and Scotland, was "walking the witch." The accused would be forcibly marched and not allowed sleep for days. Some authorities preferred this method; it spared the accused's body from violent harm, especially if they were women, so Witch Hunters argued it was humane. It wasn't — it doomed many innocents. Sleep deprivation forces the mind into a state of delirium and hallucination, so eventually victims would babble uncontrollably. Any deranged thing they said (or were told to say) was interpreted as a confession of witchcraft.
- The NKVD used sleep deprivation against its prisoners to interrogate them, as told by Menachem Begin:
"In the head of the interrogated prisoner, a haze begins to form. His spirit is wearied to death, his legs are unsteady, and he has one sole desire: to sleep... Anyone who has experienced this desire knows that not even hunger and thirst are comparable with it."
- Sleep deprivation is among the five techniques used by the Brits with Battleships during The Troubles.
