Sleep / Legends Sleep was a state of unconscious rest needed by a wide variety of species across the Galaxy , including Humans , Hutts , Gamorreans , Bothans , and Kaleesh . Interestingly , Gand required a fraction of the sleep Humans did , an ability that helped save Ooryl Qrygg ' s life on Talasea . 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 . 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 . 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 . 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 . 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 . 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 . 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 . 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 . Most beings also used blankets or sleep sack s while sleeping and slept on a sleeper .
