In Victor Hugo's "Les Misérables," the author reflects on the value of dreaming, likening it to a drug that, when taken in moderation, can provide relief from the stresses of intense intellectual effort. Dreaming serves as a soothing balm for the restless mind, allowing it to rest and rejuvenate, much like a gentle mist that softens sharp edges and smooths out rigid thoughts.

This metaphor highlights the importance of imagination and contemplation, suggesting that a little escape can harmonize our ideas and bring balance to our rational thinking. Hugo implies that while clarity is vital, a touch of dreamy reflection enriches our intellectual and emotional experiences, nurturing creativity and insight.
