The quote suggests that dreams, while they may reveal glimpses of the future, can also disrupt that future. It implies that a divine power, in this case, God, does not allow individuals to have complete foresight, as such knowledge could alter the natural course of events. The uncertainty of the future is an essential aspect of existence, as it allows for freedom and unpredictability.

Furthermore, if someone were to foresee future events through dreams or magical means, their awareness might inadvertently change those very events. The idea conveys a sense of cosmic control, emphasizing that even potential knowledge can shift the course of reality, leaving the dreamer or sorcerer in a vulnerable position. Ultimately, it reflects on the intricate relationship between destiny, free will, and the unknown.
