Sleep/Legends

Sleep was a state of unconscious rest needed by a wide variety of species across the Galaxy, including Humans, Hutts, Gamorreans, Bothans,X-Wing: Wraith Squadron and Kaleesh."The Clone Wars: The Dreams of General Grievous" Interestingly, Gand required a fraction of the sleep Humans did, an ability that helped save Ooryl Qrygg's life on Talasea.X-Wing: Rogue Squadron The Bith race of Clak'dor VII also did not sleep. Instead, they would enter a trance, during which they were almost as aware of their surrounding as awake while receiving the same amount of rest as sleeping species do when asleep. Humans and other species typically slept at night, and it was considered a necessity for proper functioning and personal performance. Lack of sleep would induce less effective performance and a bedraggled appearance in Humans, although other species might manifest a lack of sleep differently.
REM sleep was a stage of sleep necessary to most beings. If a person did not get the acquired amount, there could be repercussions, ranging from depression, exhaustion and hallucinations all the way to a possible psychotic break. The Last Jedi, p. 110
Droids could, in a manner of speaking, also sleep when they entered a powered-down state from time to time.
Reportedly, Darth Sidious killed his Master Darth Plagueis while the latter was sleeping. Afterwards, Sidious himself did not sleep, determined not to make the same mistake as his master, possibly relying on the power of the dark side of the Force to sustain himself.Dark Lord: The Rise of Darth Vader Similarly, as Bane grew more powerful in the dark side during his studies at the Sith Academy on Korriban, he almost never slept. He found that it seemed his body no longer needed sleep, feeding on his growing command of the dark side. He relied instead on an hour or two of meditation each day to keep his body energized and his mind invigorated. Nevertheless, even this power had its limits. After wandering for nearly two weeks in the wastelands of Korriban with no sleep whatsoever, Bane returned to his room at the Academy and dropped into a deep, dreamless sleep within seconds that lasted for several hours.Darth Bane: Path of Destruction
===Sleeping locations===
Humans and other bipedal species usually slept on beds or bunks, though this was not always true, especially for sentients far from buildings or ships. Many ships, including the Millennium Falcon, were equipped with cabins or bunks for the purpose of sleeping.Legacy of the Force: Tempest On planets, hotels were businesses designed to provide a place to sleep and stay the night for travelers. A common principle among military men was to sleep whenever one could wherever one could, a principle practiced by Leia Organa when she was a prisoner in Xizor's castle on Coruscant.Star Wars: Shadows of the Empire Jaina Solo, during her tour of duty in the Battle of Borleias, sought out her parents' quarters and slept in their bed as it smelled like and reminded her of them, providing a more restful, relaxing environment for her to sleep.The New Jedi Order: Enemy Lines I: Rebel Dream
===Dreams===
Some species experienced dreams while they slept. Jedi sometimes had visions of past, present, or future events while they slept. Anakin Skywalker had nightmarish visions of first his mother and later Padmé Amidala dying and in pain that prevented him from sleeping well. The nightmares of Amidala eventually became so troubling to Skywalker that he chose to forsake sleep entirely, drawing upon reserves of energy from the Force simply to keep him upright, though it could not give him rest.Star Wars: Episode III Revenge of the Sith novelization Later, his armor as Darth Vader caused him further difficulties with sleeping, due to the loud noise of the breathing and harshness on his throat. He also remained troubled by nightmares of Amidala. Disturbances in the Force could also cause Force-sensitives to awaken prematurely.The New Jedi Order: Enemy Lines II: Rebel Stand While traveling in his personal starfighter to his lair on the third moon of Vassek, General Grievous dreamed of his past as a Kaleesh warlord and the glory of victories he'd won against his foes.
===Attire===
Among some cultures, depending on economic advantage and circumstances, people wore specialized attire for sleeping, as opposed to their everyday attire. Padmé Amidala, for example, wore one of several nightgowns when she was preparing for bed or when she slept. As a Jedi, Anakin Skywalker slept without a shirt or tunic, which was different from his typical daily Jedi robes. Corran Horn undressed completely to sleep when he first joined Rogue Squadron. Similarly, on at least one occasion Aayla Secura slept without clothing save for an ornate red-and-gold floral robe that was opened wide.Star Wars Art: Visions Most beings also used blankets or sleep sacks while sleeping and slept on a sleeper.
