The shared purpose of both texts is to instruct with a moral lesson.
In the fable, the king's overprotectiveness in response to his dream ultimately leads to tragedy, illustrating the idea that attempts to control fate can lead to unforeseen consequences. Similarly, in Shakespeare's "Romeo and Juliet," Romeo's apprehension about the consequences of attending the revels foreshadows the tragic events that will unfold, highlighting themes of fate and the inevitability of destiny. Both texts convey important moral lessons about the consequences of actions and the relationship between dreams or fears and actual outcomes.
