How does Stephen R. Donaldson use imagery in Lord Foul's Bane?

Examples of Imagery:

“Gradually, the night stumbled as if stunned and wandering aimlessly into an overcast day -- limped through the wilderland of transition as though there were no knowing where the waste of darkness ended and the ashes of light began. The low clouds seemed full of grief -- tense and uneasy with accumulated woe -- and yet affectless, unable to rain, as if the air clenched itself too hard for tears. And through the dawn, Atiaran and Covenant moved heavily, unevenly, like pieces of a broken lament.”

“For a moment after his voice faltered and fell, the sanctuary was silent, and the voice throbbed like weeping, as if in his words the people recognized themselves, recognized the failure he described as their own."
