It seems that the poet William Butler Yeats wrote this to someone he loved but felt that he was inadequate in her eyes. [More powerful if you read it aloud].
Had I the heavens' embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half-light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet;
Tread softly because you tread on my dreams.
The mussar haskel: If you have children or students or friends who dream, remember, tread softly because you tread on their dreams......
