《泰坦尼克号》的主题曲名为《My Heart Will Go On》，由加拿大歌手塞琳·迪翁演唱，以下是部分歌词：
```
Every night in my dreams
I see you, I feel you
That is how I know you go on
Far across the distance
And spaces between us
You have come to show you go on
Near, far, wherever you are
I believe that the heart does go on
Once more you open the door
And you're here in my heart
And my heart will go on and on
With you
```
这首歌词通过抒情的歌词表达了主人公对爱人深切的思念和永恒不变的爱情信仰。如果您需要完整的歌词，可以告诉我，我会提供完整的歌词内容
