The quote from Stephen King’s "Firestarter" highlights the contrast between our illuminated environments and the hidden darkness that exists within them. Despite the abundance of artificial lighting in the modern world, there are still areas that remain shadowy and foreboding. This suggestion of lurking unease serves to remind us that not everything is as it seems and that darkness can exist even in the most seemingly bright places.

This theme resonates with the idea that illumination can only reveal so much, leaving some aspects of life shrouded in mystery or dread. King's words imply a duality in our surroundings, where the light may mask deeper fears or hidden truths. Thus, even in a world that strives for clarity and visibility, elements of the unknown persist, evoking a sense of caution and contemplation in the reader.
