fade这首歌表达的是一种什么样的感情

讲述一个离奇的故事，她去亚特兰蒂斯寻找一个人（或者就是寻找亚特兰蒂斯）You fade away，这个人或者地方正逐渐消失，她渴望在消失前找到。
从悬崖(或极高的地方)跃入海中，试图找寻这个神秘的地方，长久的潜水，她知道自己无法回到水面了，强迫并学会了在水下呼吸，虽然更方便了寻找，但始终找寻不到。或许亚特兰蒂斯的景色只存在于幻想之中。
最终她在绝对静寂的深海中迷失了方向，逐渐衰弱，凋零……………………………………

我只是根据歌词猜测意境，你也可以参照歌词按自己意思翻译
You were the shadow to my light

Did you feel us?

Another start

You fade away

Afraid our aim is out of sight

Wanna see us

Alive

Where are you now?

Where are you now?

Where are you now?

Was it all in my fantasy?

Where are you now?

Were you only imaginary?

Where are you now?

Atlantis

Under the sea

Under the sea

Where are you now?

Another dream

The monster's running wild inside of me

I'm faded

I'm faded

So lost, I'm faded

I'm faded

So lost, I'm faded

These shallow waters never met what I needed

I'm letting go a deeper dive

Eternal silence of the sea. I'm breathing alive

Where are you now?

Where are you now?

Under the bright but faded lights

You set my heart on fire

Where are you now?

Where are you now?

Where are you now?

Atlantis

Under the sea

Under the sea

Where are you now?

Another dream

The monster's running wild inside of me

I'm faded

I'm faded

So lost, I'm faded

I'm faded

So lost, I'm faded
