i’m sorry, but i don't know that part of the routine
i think the overall theme is materialism. throughout the whole film, the characters are more focused on material things rather than their family, mental health, and wellbeing.
the first story: the family has the opportunity to live a better and more wealthy life, and you can slowly see that the only people who care about the material things are being consumed by it. the lights represents how they are blinded by the materialistic things and the lavish lifestyle.
