Please check:

1. If a river is represents your thoughts is that an analogy or conventional symbol. I think it is an "analogy" but if it is a conventional symbol please explain why.
2.If in a story. in a brief intro, we learn about two friends and it sets us up for the rest of the story, is that the "exposition?"
3.If a song or poem is written and the narrator/poetic/songwriter remembers those dreams but it actually is that the dreams didn't happen to him, he created a "persona," correct?

1. Compare these two definitions, and then let me know what you think:

1. I think I was wrong because a symbol is one thing representing another so that would not be an analogy.

My question: if it was an analogy would it always be set up like a river is to dreams as a something is to something?
3. it could be third person ominiscent, ecept if the poem/song/story states the creator created a persona(first person) then it can't be a third person ominiscent, also?

1. Yes, if it's an analogy, it always needs to be two pairs of things compared.

3. Why not?

3.Because according to what I learning when an author creates a persona it is first person point of view not third person because it is speaking using "I" etc;

You wrote: 3.If a song or poem is written and the narrator/poetic/songwriter remembers those dreams but it actually is that the dreams didn't happen to him, he created a "persona," correct?

Are those dreams being told by a first-person character inside the third-person omniscient narrator's story, then you have two points of view because you have a story-within-a-story -- a frame story.
~ Were you given choices? If so, what are they?
~ Is that second character telling his/her story in first person?

You've set up (or have been given) a complicated storyline!

It was stated that a poet/songwriter wrote the poem/song as a first person however the dreams didn't really happen to him and then they provided an analysis essay and referred to the fact that the poet/songwriter had created a persona-that's where I'm confused

OK, that explanation makes sense. Yes, the writer created a new character (a persona) whose dreams are symbolized by that river. It it is obviously a frame story, but if that's not the focus of the question, then go with the "persona" as the answer.

1. To determine if a river representing your thoughts is an analogy or a conventional symbol, we should consider the definitions of both terms.

An analogy is a comparison between two things, typically to explain or illustrate a point. It implies that there is a similarity between the two things being compared. So, if a river is used to represent your thoughts, it would be considered an analogy because it is drawing a comparison between the river and your thoughts, suggesting some sort of similarity or connection.

On the other hand, a conventional symbol is a symbol that has a widely recognized and accepted meaning within a certain context or culture. For example, a red traffic light symbolizes "stop." In this case, the river representing your thoughts would not be a conventional symbol because there is no widely accepted meaning or association between a river and thoughts in most cultures.

2. In a story, if a brief introduction introduces two friends and sets up the rest of the story, it would typically be considered as part of the exposition. The exposition is the beginning of a story where the characters, setting, and initial situation are established. It provides readers with essential information to understand the upcoming events and conflicts.

So, the brief intro that introduces two friends and sets up the story would be part of the exposition, as it introduces the main characters and establishes the initial situation.

3. If a song, poem, or narrative is written where the narrator, poet, or songwriter remembers dreams that did not happen to them but instead, they created a persona, then yes, that would be an example of creating a persona.

A persona is a character or identity created by an author or artist to tell a story or convey certain perspectives. In this case, the narrator is adopting a fictional character or persona who has experienced the dreams being described, even though they personally did not experience them. The creation of a persona allows the writer to explore different perspectives, emotions, or experiences through a fictional lens.
