Hibernation trance Hibernation trance , healing trance , Jedi hibernation , Force trance , or recovery trance was an ability that allowed Force - users to go into a very deep hibernation state . Description . Hibernation trance was a control - based ability that slowed the user ' s metabolism and breathing to a standstill , causing the individual to only use one tenth of the air of a normal individual . To all outward appearances , the individual appears to be dead ; only thorough testing would determine that they were alive . Individuals using stethoscope s would be able to detect a faint heartbeat if they listened intently enough , and life sensor s would register a slight flicker . Other Force users with training in the Sense skill would be able to sense the hibernating individual in the Force and know they were not dead . A fully trained Force - user could stay in this state for up to one week in a dry climate or one month in a wet climate before dying from lack of water . By hooking themselves up to an intravenous water drip , they could extend the duration indefinitely . Individuals could hibernate for up to three months before dying of starvation ; the application of an intravenous sugar - solution drip could extend the hibernation period to a year . A hibernating Force - user would appear dead to all but another Force - user . This could lead to potentially dangerous results for the hibernating individual if nobody was aware of the truth . To avoid such situations , the person in a hibernation trance could provide a trigger phrase that , if recited by another person , would bring the Force - user out of the trance . Trained force - users could also use a similar technique to place others in a hibernation trance . The target had to be a willing ally . The force - user touched the ally to place him into the trance . The ally would then benefit from the effects of the hibernation trance . The ally could not emerge from the trance on his own ; he relied on the force - user to bring him out of it . A hibernation trance was a lesser form of the more advanced Force power " morichro " .
