Literally I wrote

Why are things happening literally in student creative writing? 

If “literally” is not present, does that mean things are happening metaphorically?

If “literally” is emphasis to ensure us that something is happening exactly as it’s said, does that mean other sentences embellish the details?

Or does “literally” work like a double negative with the meaning of the sentence so that we should see the exact opposite?

Or is “literally” used in a very nonliteral sense? Is it literally literal or literally nonliteral?

Is it literally necessary to use “literally”?

Is “literally” a literal word? Or is “literally” a nonliteral word?
