Final answer:
The therapist is utilizing a dream analysis technique where Eric role-plays as characters from his dream to uncover deeper psychological meaning.
Step-by-step explanation:
Eric's therapist is using the dream analysis technique known as role-play or dramatization. In this technique, the patient is encouraged to speak as if they were different characters or elements within their dream. By doing so, the therapist aims to help the patient explore the dream's content on a deeper level, often to uncover underlying emotional issues or unconscious thoughts related to the symbolism of these characters or elements. Freud believed that dreams were the "royal road" to the unconscious, suggesting that they can provide significant insights into our innermost thoughts and feelings. Jung also saw dreams as a window into the collective unconscious, filled with universal archetypes. By speaking as the moon, bats, and trees in his dream, Eric is engaging with these dream symbols to potentially uncover hidden aspects of his psyche.
