Black Rebel Motorcycle Club's "Promise"

I just listened to Black Rebel Motorcycle Club's Howl, and I noticed the line "But tread softly, you tread on my dreams" in "Promise."  I knew this was a reference to a poem, but I had to look up which specific one.  It's Yeats' "Aedh Wishes for the Cloths of Heaven," specifically the last two lines: "I have spread my dreams under your feet; / Tread softly because you tread on my dreams."
