夏の憂鬱
L'Arc~en~Ciel Lyrics

The lyrics of L'Arc~en~Ciel's song 夏の憂鬱 (Natsu no Yuuutsu, or "Summer melancholy") depict a sense of nostalgia for a summer that has passed, and a longing for a person who has been lost. The singer describes feeling unable to sleep because of the weight of the summer melancholy, and finding his gaze captured by the hypnotic waves. The summer winds blow and the person he longs for appears in his mind as a memory he tries to chase after. The sun shines too brightly in his eyes and it makes it difficult to see clearly.

The chorus talks about how the summer melancholy has overwhelmed the singer, causing him to lose sight of the person he loves. He then describes the person as disappearing like a bird swimming in the unreachable sky. The final verses talk about the sunset heralding the end of summer and the coming of autumn. The singer laments the loss of sleep and the loss of his love, and questions what he should believe in in order to move forward.

Overall, the lyrics create a dreamlike and bittersweet atmosphere, evoking the ephemeral nature of summer and the pain of loss. The use of natural imagery, such as the waves, the wind, and the sun, helps to create a sensory and immersive experience for the listener.
