In James Cameron's 'Avatar' what does it mean when Colonel Quaritch says 'You don't dream in cryo'?

Answer 1

Cryo is short for cryogenics. Cryogenics is a branch of physics that deals with very low temperatures, and theories are working to find ways to cryogenically freeze living organisms and revive them at a later date. Some ideas are to freeze people who have incurable diseases and then revive them at a future date when a cure or treatment is available. In the case of Avatar and many other Science Fiction stories, the idea is to put space travelers in cryo to travel very long distances that would be too great for the average human lifespan.

In reference to the quote "You don't dream in cryo," the theories behind cryogenics would put a person in a state where all body functions, including brain activity, would cease and turned over to life support systems.
