Syntax: This uses the present perfect tense ('We got it together') to indicate a past action with present relevance. The tag questions ('didn't we?', 'don't we baby?') are used to seek agreement or confirmation, softening the statement.
Morphology: 'Got' is the past participle of 'get'. 'Together' functions as an adverb modifying the phrasal verb 'got it'. 'Definitely' is an adverb of certainty modifying the verb phrase.

Syntax: The structure uses a series of parallel noun phrases with possessive pronouns ('my first, my last, my everything', 'my sun, my moon, my guiding star'). This parallelism creates a rhythmic, emphatic list of attributes.
Morphology: 'First' and 'last' are superlative adjectives used as nouns. 'Everything' is an indefinite pronoun. 'Guiding' is a present participle used as an adjective to describe 'star'.

Syntax: The sentence uses the existential 'there is' structure to state existence ('there's only one'). The repetition of 'only' adds emphasis. The second line is a conditional-like statement about an impossible past creation.
Morphology: 'Only' is an adverb modifying 'one'. 'Could have made' is a modal perfect construction ('could' + have + past participle 'made'), expressing a past possibility that did not happen.

Syntax: This is a compound sentence joined by the conjunction 'yet', which shows contrast. The structure 'You're X, yet I'm Y' establishes the central paradox.
Morphology: 'Reality' is an abstract noun. 'Lost' is an adjective describing the state of the subject 'I'. 'In a dream' is a prepositional phrase acting as an adverbial complement.

Syntax: The first line is a question starting with 'Can't you see', followed by a conditional 'if' clause. The second line is a simile introduced by 'You're like...'.
Morphology: 'Make me feel' uses a causative verb 'make' followed by a bare infinitive 'feel'. 'Dew' is an uncountable noun. 'Brand new' is a fixed adjective phrase modifying 'day'.
