Declaring people in prolonged coma to be dead was quite common during the Victorian era. The lucky ones often woke up at their funerals, while the unluckier and unfortunate ones woke up in their graves, where they probably later died. This led to the introduction of “waiting mortuaries,†where the bodies of dead people were taken until they began to decay. Waiting mortuaries didn’t help much, since more dead people ended up there than living, so “safety coffins†were introduced.
Safety coffins were just like normal coffins except that they had tools and apparatuses that a “dead†person could use to either escape from the coffin or to inform people above that they were still alive. Some safety coffins had strings that rang a bell above the ground whenever they were pulled or if the “corpse†moved. Others exposed a flag above the ground whenever the supposedly dead person blew air into a tube. Others had ladders that the person could simply use to climb out of the grave. --
