The Malvina Reynolds song "Uneasy Dreams" comes to mind.

UNEASY DREAMS -- Malvina Reynolds

Uneasy dreams, when I can't find you,
You catch a train that passes me by,
Or we are lost in some big city,
And I can not find you, tho I hear you cry.

When I awake, you're here beside me,
You're in my arms where you should be,
But when I'm sleeping, my heart is weeping,
What can they mean, those uneasy dreams.

When I come home and you are waiting,
I am so sure your love is true,
But when I'm sleeping that dream comes creeping,
That tells me some day I'll be losing you.

Then there is the John Hartford song "In Tall Buildings".
...So it's goodbye to the sunshine, goodbye to the dew
And goodbye to the flowers and goodbye to you
I'm off to the subway, I must not be late
I'm goin' to work in tall buildings.
