A German teenager accidentally climbed out of a fourth-floor window and fell 10 meters (30 feet), to the ground where he kept on sleeping, albeit with a broken arm and leg.

A teenage sleepwalker stepped out of a fourth-story window of his apartment and fell 10 meters to the ground, where he continued to sleep and was found by police.

The 17-year-old had just moved into a new flat in the eastern town of Demmin with his sister. He went walking on Sunday night and climbed out of the window after stepping on a cardboard box, police said.

His sister said her brother often sleepwalked. The boy hadn’t taken drugs or drunk any alcohol.

I guess he can sleep though anything.  If I was him I would lock the windows from the outside.
