Police say a 41-year-old car washer shocked his family when he interrupted a funeral being held for him at his mother's home in the town of Alagoinhas in north-eastern Brazil.
Police inspector Roberto Lima said that on Sunday Jose Marcos Araujo identified a body at the city morgue as being that of his brother, Gilberto.
Insp Lima said that Jose Marcos took the body to his mother's home where a wake was held.
But the police inspector said that several hours before the Monday burial "a friend of Gilberto's saw him walking down the street and told him that his family was mourning him".
"So he went to his mother's home to let everyone know he was very much alive," Insp Lima said.
