It's been used as a theme in films for many years. Makes you think, though, doesn't it?

Poor young woman, hope she survives.

> “My heart is so heavy. Someone pronounced my child dead, and she’s not even dead,” Beauchamp's mother, Erica Lattimore, told WDIV-TV.

Of all the things she might have said, what a strange thing to say.

How scary, hope she makes a good recovery.

Nightmare! My mum was so scared of being buried alive that she inserted a clause in her Will insisting that her veins were to be opened to check that she was really dead. A practical lady.

It did happen quite often, I believe and was the origin of a bell being placed by a grave with a string going down to the coffin so that any suddenly revived 'dead' person could ring for attention and be dug up again. I checked-up and the phrase 'dead ringer' comes from this custom - although I'm not sure how it came to mean someone looking just like someone else.

^ That's where 'graveyard shift', 'dead ringer' and 'saved by the bell' come from.

Not true:

Other sources agree.

saved by the bill is boxing, I think. Many a boxer has been saved by the bell but I'd be surprised if many people buried alive have been.

Happened to my mother after an operation when she was 20. Pronounced dead , she was being wheeled down the corridor to the morgue. Fortunately one of the porters saw the cover moving and she lived to tell the tale.
