In Jade Bird's song "Side Effects," the singer suggests escaping and going on a spontaneous adventure. The lyrics also touch on the idea that being in love can change a person's perspective and make them question who they are. The song also addresses the fear and uncertainty that can come with making big life changes. The chorus of the song asks for a sign from the person she's singing to, indicating that she is willing to leave with them whenever they're ready. The repeated phrase "It's just a side effect of changing your life" suggests that the fear and uncertainty mentioned earlier are normal and to be expected when making big changes. Overall, the song is about taking risks and facing the unknown, all while having someone by your side to support you.
