The dependent clause of the sentence is "If we are going to make it to the movie on time," because it depends on the next part of the sentence to make sense. Without the next half of the sentence, the clause left alone wouldn't make any sense. The other clause is independent, meaning that it still makes sense when it stands without the dependent clause.
I believe it is a metaphor as falling from cloud 9 was usually used in older movies to express that they had fallen in love
lets see, okay its B im not good at explain sorry!
