In the book "Sleep" by Haruki Murakami, the protagonist reflects on the surreal sense of existence that permeates their life. They feel as if their very being and experiences are akin to a dream, highlighting a deep disconnect with reality. This perception is intensified by the physical forces of nature, such as a strong wind, which evokes a fear of being swept away to an unknown place where they could lose their identity and autonomy.

The struggle to maintain a sense of self is palpable as the protagonist attempts to anchor themselves amidst the overwhelming sensations and fears. They tell themselves to "hold tight," yet find no tangible support in their environment, symbolizing a broader existential anxiety. This narrative encapsulates themes of uncertainty and the search for stability in a world that often feels chaotic and ungraspable.
