Generate an image symbolizing the feeling of being tired. It spans a calm, serene, and dimly lit environment. A comfortable armchair sits in front of a low-burning fireplace. The colors are muted, using a palette of twilight blues, soft grays, and warming ambers. A thick, open book lays gently on the armrest, halfway read, a clear symbol of someone winding down and preparing for sleep. Soft pillows give an impression of comfort and safety. An old-fashioned wall clock ticks softly in the background, signifying the late hour.
