How does the author use foreshadowing in A Shining Affliction: A Story of Harm and Healing in Psychotherapy?

In Chapter Seventeen, Annie shares an important fact about herself..... that she had been a patient of Dr. Connelly. The fact that Annie had undergone psychiatric treatment in the past was foreshadowed in Annie's relationship with Ben. At one point, she even wrote that the same black bird that had touched Ben's life had also touched hers.
