"Thud."
The light from the corridor was completely cut off.
As far as she could see, the room was engulfed in darkness, yet she did not turn on the light; instead, she leaned against the door, standing there silently.
The world one sees in the dark is quite intriguing: a person's eyeballs will slowly adapt to the lack of light, and those with normal vision won't become completely blind; however, the faint light and reflections make it impossible to see the full outline of objects, often only catching glimpses of edges and contours submerged in dimness.
At this point, the brain starts to exercise its excess functions: it begins to fill in any unclear images with a rich imagination—since humans are instinctively afraid of the dark, this kind of imagination often quickly constructs omnipresent threats.
