Ananova:

An 84-year-old Polish woman woke up in a hospital morgue after being declared dead by her doctor.

The error was noticed only when someone saw her body bag in the morgue moving, police said.

The woman, from the village of Jablonowo, fell unconscious and her husband called an ambulance.

A doctor from the emergency medical services pronounced her dead, a police spokesman said.

"A funeral company took the body to the morgue. 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."

The woman was taken to hospital in the nearby town of Zwolen and placed in intensive care. Police have launched an investigation.
