The Twilight Zone often had twist endings, and though some of them have now been overused in movies and TV, one of its episodes has the best use of the “they were dead the whole time” twist. Created (and hosted) by Rod Serling, The Twilight Zone premiered on CBS in 1959, ending in 1964 after five successful seasons. Each episode of The Twilight Zone told a standalone story, with its characters usually going through unusual and disturbing events, most of which had a horror and/or sci-fi tone.
