How does the author use foreshadowing in Reading in the Dark?

The opening of Chapter One, when the boy's mother warns him of a troubled spirit on their staircase, foreshadows many other incidents and stories throughout the novel in which living people are affected by their supernatural beliefs. The opening scene also spookily foreshadows the closing scene of the novel, in which the boy stands on the same stairs on the eve of his father's funeral; his father had been troubled and in sadness throughout his life.
