Read the excerpt from walden.
[a]s the sun arose, i saw it [the pond] throwing off its nightly clothing of mist, and here and there, by degrees, its soft ripples or its smooth reflecting surface was revealed, while the mists, like ghosts, were stealthily withdrawing in every direction into the woods, as at the breaking up of some nocturnal conventicle [secret meeting].
in the excerpt, thoreau uses imagery to describe
fog slowly rising from the surface of the pond.
a fierce wind blowing water across the pond.
insects floating peacefully above the pond.
a soft, warm light shining on the pond.

figurative language is a resource that fiction writers use to make better descriptions of what they want to write about or express. they can improve their stories, as they can elaborate more vivid and colorful sentences. this way, the reader will be able to have more detailed images in his/her mind.

places, objects, people and even feelings or emotions can be described with a lot of detail to metaphors, similes and personifications. making different kinds of comparisons to make a description more specific, as well as assigning human qualities to non-human objects (and vice-versa) can be very useful for science fiction writers.  

on the other hand, alliterations allow writers to elaborate more entertaining and creative sentences. it consists in using a sequence of words that start with the same consonant letter. they can be used to emphasize something important the writer wants to express, or just as a fun literary device.
