The song "Flat World" by Shane Harper tells a story of a person who used to live in a world that lacked excitement and diversity. In this world, everything was dull and monotonous, represented by the colors being the same, mainly white, black, and grey. The town they lived in was also devoid of any life, with silent birds and no signs of progress like rockets launching. However, everything changes when the person encounters someone special, represented by the line "You're like a rush of blood to my head." This person brings vibrancy and energy into their life, like ice-cold water running down their neck or hot coals under their feet. The world suddenly becomes brighter and clearer. The person realizes that being with this special someone makes them feel like they are floating into the atmosphere, implying a sense of freedom and elation. However, they also feel unworthy of the love and presence of this person, feeling that they are "too good" for them. Despite their insecurities, this person remains in their life, causing the protagonist to question why they would still stay. The song ends with the chorus repeating that the protagonist must have been asleep before, implying they were living a mundane life until this special person came along. Overall, "Flat World" tells a story of someone who experiences a transformative love that brings joy, excitement, and color into their previously mundane existence.
