In the seventeenth, eighteenth and nineteenth centuries, this fear seemed to reach epic proportions, evidenced by a series of inventions: specialized, safety coffins with an attached bell and pulley system. These systems were designed so that if one awoke after being buried, they could ring the bell and be rescued. Families often hired grave diggers to wait up through the night just in case a bell rang. This practice encouraged the phrases, "saved by the bell", "dead ringer" and "graveyard shift".
When I was small, I frequently endured status epileptics of the convulsive type. At age 35, I went for a blood test and suffered a massive, violent tonic-clonic event and the folks in the Cigna lab thought I had died in the chair from it. All of them left the room and turned out the lights. Only thanks to my husband, who has experience with my epileptic states, was I not carted out by a coroner.
For me, the idea that one might be perceived dead when she was not seemed possible. I read Poe's short story "Berenice" and a few others by Poe. It seemed to confirm my worst fears, until I really began thinking about it. Still, as calm as I have learned to be, I have told my family NOT to cremate me and to definitely "wake" me for at least three days... And, DO NOT enbalm me.
Just keep me chilled and all will be well...
I think that's reasonable!
