A Dream within a Dream
Concession to accusation
Someone has accused him of living in fantasy. Instead of defending himself, he agrees—then pivots to ask whether it matters.
Hope's timeline
The speed doesn't matter—'night,' 'day,' 'vision,' 'none'—hope is still gone. He's listing possibilities to show they're all equally devastating.
Nested unreality
Not just 'life is a dream' but a dream *within* a dream—two layers of illusion. Reality is twice removed.
Sand as seconds
Classic tempus fugit image, but notice 'How few!'—he's shocked by how little time he has, not how much has passed.
Tighter clasp
The desperation escalates—first just holding, then grasping, then trying to *save* even one grain. Futility in three stages.
