Determining Central Ideas in a Fictional Passage

Consider the following excerpt from a fictional short story:

In a world where dreams are traded as currency, people are torn between the desires they wish to fulfill and the value of their aspirations. Each transaction brings a fleeting sense of happiness, yet leaves behind a longing for what was sacrificed. The protagonist, Lyra, faces a dilemma: should she trade her most cherished dream for immediate gratification or hold onto it at the cost of suffering? As she navigates this moral landscape, she discovers that true fulfillment may come not from dreams realized but from the journey itself.
