The lyrics describe the feeling of falling for this person and being captivated by their laughter and presence. The singer expresses their love and hopes that the person they are drawn to will know about their feelings. The mention of the mosque and praying suggests a setting of religious significance, and the emotions described in the song seem to convey a sense of longing and admiration. The use of "Vertical Horizon" could symbolize a sense of reaching for something beyond the ordinary, such as a spiritual connection or a higher level of emotion. Overall, the song appears to be about the experience of developing feelings for someone in a unique and potentially challenging setting, and the longing for those feelings to be reciprocated.
