Throughout the beginning of Slaughterhouse 5, Vonnegut describes how Billy has "time-traveled" throughout his life. "Billy blinked in 1958, traveled in time to 1961."(Vonnegut 46) When discussing time travel, it is inferred that what he is explaining is Billy's Post Traumatic Stress Disorder and how he moves from present-time reality, to his past during the war. These transitions connect the ideas of how he transforms throughout his life, decisions in the past reflecting on his attitude in the present. During the book, the way he time-travels is not in a uniform fashion, one chapter in the past to one in the present, but more in a jumbled order similar to how people actually function with PTSD. During discussions we came to the conclusion on how his time-traveling through PTSD connects events to what is happening in his current life. “Billy slept without dreaming for a while, and then he traveled in time. He woke up with his head under a blanket in a ward for nonviolent mental patients… It was springtime in 1948, three years after the end of the war.”(Vonnegut 99) Before traveling to the ward, Billy is in the time of war when he was in the “hospital” in his camp, put under morphine. The purpose of his time traveling is to connect how his past life during the war ultimately affected how his future ended, and how his PTSD relates to his view on life.
