For both the story and histrory there is only historien in Danish?
Om bjørnen? Han løb væk med mandens bildelene!
A "storey" is a level or floor of a building, a "story" is an account of events, either imaginary or real.
So "storey" is quite surely not the thing one is telling.
Does this mean history repeats itself or is it literally saying the story is told again and again
"Grandpa, you have told this story so many times!"
"Histroy repeats itself" would be more along the lines of "Historien gentager sig."
