what does " It felt like it was happening to my double" means? PARIS (AP) -- French novelist Patrick Modiano has devoted his career to exploring the traumas of the Nazi occupation of his country, including how it could strip people of their identities. On Thursday, the 69-year-old Parisian's steadfast efforts over the past 45 years earned him the 2014 Nobel Prize in literature. In a sign of how effective his works have been, his 1968 "La Place de l'Etoile" was later hailed in Germany as a key post-Holocaust work. Modiano was out for a walk on Paris' Left Bank when he received word of his prize. "I was walking near the Luxembourg Gardens when my daughter called with the news," Modiano said at a news conference at the offices of his French publisher Gallimard. "It came as a complete surprise, I just kept walking. It felt like it was happening to my double." He was at a loss when asked how he would celebrate his win. what does " It felt like it was happening to my double" means?
