The character experiences a profound sense of disconnection from Tollygunge, a place that once held significance for him. This feeling resembles the transition from the dream state to waking life, where the boundaries and meanings of dreams dissipate under the clarity of reality. It highlights a moment of existential reflection, suggesting that what seemed relevant or coherent in one context can lose its meaning when faced with the truths of the world outside.

In this context, the individual's departure from Tollygunge symbolizes a broader shift in perspective. The narrative implies that life often confronts us with new realities that can irrevocably change our understanding of our past. The line captures the essence of moving on, as well as the often jarring differentiation between dreams and reality, evoking a sense of loss and liberation simultaneously.
