A dream for us

Cause what i feel inside
I dont want to hide
It's you that got to me
Its what i want to sing
Cause i've got a dream for us
Running through my mind
Sitting on the beach
Looking at the sea
And we're old and tired
And time has made us smile
As we go on counting things
People in the breeze
We're not the only ones
There's hundreds on the shore
Looking at the sea
But it's just you and me
If the day never comes
I sink beneath the tide
Will you still be with me
Or disappear?
