The quote from Victor Hugo's "Les Miserables" reflects the challenges of a restless mind after a busy day filled with various experiences and concerns. It highlights how one can initially fall asleep but struggles to return to a peaceful state of slumber when awakened. This emphasizes the difficulty of regaining restful sleep once disturbed, contrasting the initial ease of drifting off.

Hugo captures a universal experience many face, where thoughts and sensations from the day linger in the mind, making sleep elusive. This illustrates the connection between our daily lives and our ability to find tranquility at night, suggesting that the pressures of daily life can significantly impact our rest and well-being.
