The strange incident took place in the town of Zirndorf in northern Bavaria on Sunday evening, reports the Augsburger Allgemeine.
When police arrived at the scene they discovered a 26-year-old man inside the coffin. But far from being a corpse, he was merely trying to get a few winks of sleep.
The man explained that he had recently bought the coffin and had refurbished it to make it comfortable for sleeping in.
After he promised to stop sleeping in his coffin in public spaces the police decided to take no further action.
