This thesis aims to explore how the idea of American Dream is presented in White Noise, how the Dream is represented as ¡§American magic,¡¨ and how eventually it turns into ¡§American dread,¡¨ the ultimate American nightmare. In Chapter One, I provide a brief historical survey on the concept of the American Dream, the idea that mainly shaped the American nation in history. I turn to Jim Cullen¡¦s The American Dream: A Short History of an Idea That Shaped a Nation and Andrew Delbanco¡¦s The Real American Dream: A Meditation on Hope to explore how the idea of the American Dream changes through the course of American history as well as construct a historical background of the American Dream. Chapter Two explores how the American Dream in White Noise is exposed and transformed into what DeLillo terms in the novel as the ¡§American magic¡¨ via the novel¡¦s extreme emphasis on the issue of mass media, the operation of simulated magic. First, I briefly analyze the American Dream succeeded in White Noise based on my survey of the American Dream in the previous chapter. Reading DeLillo¡¦s ¡§American magic¡¨ as the simulated dream in White Noise in light of Baudrillard¡¦s theory of simulacra and simulation, I argue that White Noise is in fact a novel based on the critique of the American Dream due to the falsehood of the protagonists¡¦ American Dream televised through media and consumer culture. In Chapter Three, by recalling the novel¡¦s emphasis on the protagonists¡¦ fear of death, I aim to examine the true reason for such fatal fear. While many may read White Noise simply as a postmodern representation of man¡¦s uncontrollable natural fear of death, I examine the connection of this major theme of fear towards death to DeLillo¡¦s American magic and point out the possibility of American magic acting both as a cause and reinforcement of this fear as well as relating it to the larger issue of DeLillo¡¦s ¡§American dread¡¨ ¡Xa portrayal of the American Dream and magic brought to its extremity and stirred towards a possible apocalyptic end.
