The concept of memory encompasses both personal and shared experiences, suggesting that our identity is shaped by how we remember events individually and collectively. This interplay is crucial as it forms the foundation of our understanding of who we are. In essence, our individual memories contribute to a larger tapestry that represents our culture and heritage.

Haruki Murakami in "1Q84" emphasizes the importance of history as a collective memory. When this collective memory is altered or erased, it poses a significant threat to our perception of reality and identity. Without access to an authentic collective history, individuals can struggle to maintain a sense of self, leading to a disconnection from their true identity.
