The statement reflects the idea that shooting stars, often invoked for making wishes, are not actual stars but rather meteoroids that ignite upon entering the Earth's atmosphere. This phenomenon creates a brief yet captivating visual display, which is mistakenly romanticized as celestial wishes granting instruments.
This metaphor serves to highlight the disillusionment that can accompany our desires and expectations. Just as a shooting star merely leaves behind a trail of debris, the things we wish for might not hold the substance or magic we imagine; they can be fleeting and illusory, reminding us of the transient nature of life and hope.
