My short story plot would be during the Cold War era and have a man that keeps having this dream of a nuclear war. He has no recollection of what happened during his dreams other than occasional flashbacks.  Every time he wakes up at the same part to the sound of his alarm.  The character is a relatively normal guy other than the fact he works for the government (Homeland security and Defense).  It is during the height of the cuban missile crisis in 1962 when the US ship Beale was threatening the Soviet Nuclear submarine to surface.  Instead of the soviet ship deciding not to attack they launch their lone nuclear tipped missile at the Beale.  The US blockade around cuba is decimated and world war 3 begins.  The characters job was to communicate with the US forces at their stations and he gave the orders to the Beale.
