is put into a state of suspended animation using a drug or a chamber or something very cold and it is a common sci-fi trope. It may be called a way to cheat death, where a person's life form may be suspended in -200 degrees Celsius and probably preserved in liquid nitrogen.

Therapeutic hypothermia. The astronaut's body temperature is lowered to about 90 F (32 C), putting them into a hibernation like sleep called torpor. This state dramatically lowers the metabolism, reducing caloric intake needs and slowing muscle atrophy. The film showed full body immersion in fluid.
Do astronauts hibernate?
Some day, astronauts packed into rocketing tin cans bound for other planets may be protected from radiation and space sickness by having their metabolisms depressed to a fraction of their typical rate. They'll hibernate like bears as they hurtle through space for months at a time.
What happens to a frozen body?
When scientists attempt to freeze a sample of living human tissue, like a slice of liver, “the tissue is completely obliterated, the cell membrane is completely destroyed. So there's actually no proof that you're preserving anything, and that's because the science is just not there yet.”
