Final answer:
In the field of psychology, repressed memories can be locked away due to trauma. Disturbing these memories can cause emotional upheaval and distress.
Step-by-step explanation:
The question is asking why memories should be disturbed if they are locked away. In the field of psychology, repressed memories refer to memories that are unconsciously blocked due to the trauma or distress associated with them. These memories can be powerful and can have a significant impact on a person's mental health and well-being. Therefore, disturbing these memories can potentially cause emotional upheaval and distress.
