Yes, you may incorporate diary entries as a form of imaginative writing. Below is some useful information to consider regarding diary entries:
Diary entries may include the writer's experiences in addition to thoughts and feelings and include comments or commentary outside of the experience. Diary entries may not always be exciting. Diary entries can also be deeply intimate or personal. They may record the writer's personal thoughts with the intention of immortalising a thought or feeling on paper for themselves only, often which would not be communicated to anyone else. Similarly, diary entries can also be deeply impersonal. They may be written with the anticipation that they will be read, and as such, be limited in their self-expression and contain only factual information about an event.
Other forms of imaginative writing you can utilise include:
- Memoir
- Monologue
- Letter
- Autobiography
