Answer:
Imagery
Step-by-step explanation:
Imagery is the use of vivid, descriptive and figurative language that is employed by an author in order to paint a picture in the reader's mind. In this excerpt, we learn that the speaker is a girl with a very powerful imagination. In order to convey how imaginative the girl is, the author provides some examples. We learn that the girl imagines herself as a fictional character living a great variety of adventures. These images are particularly vivid due to the descriptive language that the author employs.
