The woman, from the village of Jablonowo in central Poland, was pronounced dead by a doctor from the emergency medical services after her husband called an ambulance...

"A funeral company took the body to the morgue," a police spokesman told the Telegraph. "Several hours later, a worker there noticed the bag containing the body was moving," he said. "He called a doctor who noted the woman's vital functions had returned."...

This reminds me of a story I saw years ago on "Alfred Hitchcock Presents" when a man is paralyzed in a car accident and pronounced dead, despite being very much alive. To his horror, he's taken to the autopsy room to be hacked into, but he manages to 'almost' save himself by crying a single tear to show he's still alive.

All through the show, the man continues talking and trying to convince those looking after his body --that he is 'still alive'.

That one episode (along with a couple of others about being buried alive) during my younger years caused me to forever fear what happens when you die or can't respond to medical professionals.
