Wonderful Nightmare

Wonderful Nightmare (lit. Miss Wife) is a 2015 South Korean fantasy romantic comedy film starring Uhm Jung-hwa and Song Seung-heon.

The early Korean working title literally translates to Wonderful Nightmare, which was retained for the international English title.

Plot
Yeon-woo is a successful lawyer who gets into an automobile accident leading her to fall into a coma. She wakes in heaven to find that her death was a clerical error and it was actually an old woman with the same name who was meant to die.

To hide the mistake, she is asked to live as another woman – a housewife who was also killed by mistake – for just one month. Married to a very ordinary civil servant named Sung-hwan with a difficult teenage daughter and a precocious six-year-old, Yeon-woo finds herself changing in unexpected ways as well as facing challenges she hasn't faced before.
