The closest thing was on Dallas. At the end of the 1984-85 season, Bobby Ewing, played by star Patrick Duffy, was killed off. But at the end of the 1985-86 season they had Ewing s widow wake up to find him in their bathroom taking a shower. The show explained that his murder, and the entire 85-86 season up til then, was a dream on the part of Bobby s wife. While they didn t redo the season, they wrote off it s events and continued the show as if it never happened.
