In Haruki Murakami's book "Yesterday," the concept of dreams is explored as something that can be shared between people. The quote suggests that dreams are not merely personal aspirations but can also be communal experiences that we can offer to others or take inspiration from. This metaphor evokes the idea that dreams can be borrowed or lent, signifying their fluid and transient nature within our lives.

The notion of lending and borrowing dreams emphasizes the interconnectedness of human experiences. It highlights how one's aspirations can resonate with others, fostering a sense of empathy and understanding. In this way, Murakami invites readers to consider how their own dreams may impact those around them, reinforcing the importance of connections and shared journeys in the pursuit of personal goals.
