Answer:
No.
Explanation:
A metaphor is a figure of speech in which an object or action is said to be another, to which it is not literally applicable.
Examples:
The author isn't trying to 'create a creepy mood' by using a metaphor because the phrase 'you could see the moon reflected in them' isn't a metaphor. It is literally applicable. If the author uses this phrase to describe Jack's or another character's shoes, it probably just means that the shoes are really shiny.
