Hibernation trance, healing trance,[2]Jedi hibernation, Force trance, or recovery trance was a control-based ability that would allow Force-users to go into a very deep hibernation state. This 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. 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.
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.[3]
Force-users could also use a similar technique to place others in hibernation stance.
A hibernation trance was a lesser form of the more advanced Force power morichro.[source?]
