* Metaphor: The song uses the "last night" as a metaphor for the experience of feeling lost and alone. It's not necessarily about a literal event, but rather a feeling of being "lost in the dark."
* Imagery: The lyrics paint vivid images in the listener's mind, like "the shadow of the night is closing in" and "the cold is creeping in." This helps to create a sense of atmosphere and evoke emotions.
* Personification: In lines like "the night is getting darker," the night is given human-like qualities of becoming "darker," which suggests a sense of impending doom and a feeling of being swallowed by the darkness.
* Repetition: The phrase "last night" is repeated throughout the song, creating emphasis and emphasizing the cyclical nature of the feeling of loneliness and despair.
* Symbolism: The "shadow" can be interpreted as a symbol of doubt, fear, or the feeling of being unseen or unheard. The "light" could represent hope or a way out of the darkness.
It's important to note that the effectiveness of these literary devices lies in how they contribute to the song's overall theme and message, which is a struggle with loneliness and a longing for connection.
While "Last Night" may not be a heavily literary work, these devices help create a powerful and relatable emotional experience for the listener.
