Whereby sleep shows (Swinburne)

For who sleeps once and sees the secret light
Whereby sleep shows the soul a fairer way
Between the rise and rest of day and night,
Shall care no more to fare as all men may,
But be his place of pain or of delight,
There shall he dwell, beholding night as day.

Algernon Charles Swinburne, from "Sestina"
