@Tisquares can't believe I really forgot it, got lost while studying. SO.
Here's the theme is “lost dreams and hope by dawn”. You know when you fall asleep and have those dreams that you don't know if you'll achieve them? Sometimes they burden you and even seen more like nightmares than dreams. You wake up in a daze, covered in sweat and a bit, unsure how to proceed. You hear birds chirping nearby and open your curtains… and there, at the horizon, is the sun. Rising up for a new day.
You don't know what the future holds for you, but you know you'll try your best to get there.
