Under anaesthesia like propofol your brain literally pauses, when you wake up you are typically confused because it’s like you were literally paused and resumed
Hamsters and other small animals can be and are regularly frozen and unfrozen
Propofol slows down your brain and changes several “rhythms”, but your brain activity does not cease at any point. To your conscious self it may appear as if you’ve “paused”, but this is absolutely not the case.
Hamsters and small animals can be partially frozen and unfrozen. Once fully frozen (or close to it) they can no longer be revived. Once brain cells die, they cannot be revived.
His study showed that every animal in which 15% or less of the body water had been frozen recovered completely. Two-thirds of those in which 15 to 40%, and one-third of those in which 40 to 50% of the water had been frozen were fully resuscitated and survived long periods.
Hamsters in which 55 to 70% of the water had been frozen subsequently recovered heart beats and breathing but not consciousness, whereas when 76% of the body water had been in the form of ice resumption of heart beat was the only sign of life.

That’s literally not how it works.
