歌詞
Overnight, I dreamed of the girl
Who brought me fresh flowers before
Standing across, I can see through the wire fence
Am I scary? Or why is she looking at me in fear?
There’s a war inside of me all my life
Are we trying to find out who is guilty
by being one of the guilty?
I sing a distant song of love and redemption
For the moments of suffering in my nightmare
Run my girl, with all your strength, to serenity
Take bravery and purity with you
Never ever come back, forget me please
‘Cause your kindness left me afraid of
what tomorrow may bring
I would rather get lost in my solitude
So long it takes to verify an assume
I dare not think about it what if real
I sing a distant song of love and redemption
For the moments of suffering in my nightmare
血色墜入夢境，洇染雙面迷局。
以真理之心踏過墟宇，找尋片刻光明。
