The song "Lighthouse" by Joe Jonas tells the story of a person who is feeling abandoned and trapped in their emotions. They reminisce about asking someone to stay with them and being assured that they would return someday. However, that person did not uphold their promise, leaving the speaker feeling lost and confused. The lyrics describe a metaphorical lighthouse in which the speaker finds themselves. This lighthouse represents their isolated and lonely state. It has no windows, symbolizing a lack of clarity and understanding. The speaker is searching for answers to why they were left behind but feels unable to find any. As time passes, the speaker's heart grows colder, and they yearn for the chance to see the person they miss. However, all they see are the walls surrounding them, emphasizing their growing desperation and loneliness. They feel as if they are going crazy, unable to escape the confines of their emotions. The cliff mentioned in the song represents the speaker's emotions, which are too intense and challenging to overcome. They long for the person who left them to come back and save them from the pain they are feeling. The speaker believes that their tears are overwhelming and will create a waterfall, symbolizing their emotional turmoil. Ultimately, the speaker realizes that they are stuck in the lighthouse, unable to escape their emotions. They acknowledge that there are no answers or ways to be found through the fog of their feelings. The lyrics convey a sense of longing, abandonment, and the inability to move forward from heartbreak.
