Star dirt

We desire it and chase it, we hunt it down.
The expectation of what it will bring, swirls around and around.
But if we could grab it and jar it to keep, hoping for a million angels on which we would sleep.
Soon we'd be wanting anything more, for all you had captured was dirt from the floor.
As stardust and good luck, magical wishes, all happen in dreams.
Where any things possible, or so it seems.
But a jar of stardust, is only the dirt from the floor. Nothing less and not any more.
