Woman dies at her own funeral.

From Daily Mail:

A woman died from a heart attack caused by shock after waking up to discover she had been declared dead - and was being prepared for burial.

As mourning relatives filed past her open coffin the supposedly dead woman suddenly woke up and started screaming as she realised where she was.

Fagilyu Mukhametzyanov, 49, had been wrongly declared deceased by doctors but died for real after hearing mourners saying prayers for her soul to be taken up to heaven in Kazan, Russia.
