As in Dandelion Wine, Bradbury infuses the novel with nostalgia for his childhood. However, Dandelion Wine embodies the idyllic memories of youth, whereas Something Wicked This Way Comes superimposes folk-tale and supernatural elements over a small-town Americana setting in order to explore the dark undercurrents that surround the transition to adulthood.[6]
The novel also conveys the theme that the power that people, objects, and ideas have over to some individual depends on the power the individual instills in them with own mind. Because of this, the carnival is able to easily take advantage of the common human fears of aging, death, and loneliness which everyone has or relates to.[7]
Self-centered desires and wishes are portrayed as the base of human malice and unhappiness because they blind people to the blessings of life with an unattainable dream. The novel's main example of this is Miss Foley's seduction by Cooger's promise of youth that causes her to fail to see his deception as her "nephew" and lose her rightful place in society.[8]
It is implied that the counter-force against this is acceptance of one's faults and an enthusiastic pursuit of the everyday joys of life, signified by Charles' spontaneous running with Jim and Will at the end of the novel. The fact that he is nearly forty years older than them pales in comparison to the pleasure he gains from simple human companionship.[9]
