Can you give me An example of foreshadow in a monster calls?

In "A Monster Calls" by Patrick Ness, one instance of foreshadowing occurs when Conor O'Malley repeatedly dreams about a strange, dark figure. This figure symbolizes his internal struggles and the impending loss of his mother due to cancer. The monster's arrival hints at the difficult truths Conor will have to confront, indicating that he must face his fears and emotions rather than avoid them.
