In That Sleep of Death What Dreams May Come?

O grant me darkness! Let no gleam
Recall the visionary ray!
Give me to sleep without a dream.
Too often have I dreamt by day.
The dreams of day are all too strong;
Give me undreaming sleep, and long.

If blackest night be of the stuft
Whereof sun-woven days are made,
I that have dreamed, and dreamed enough
Tremble, of dreamier dreams afraid.
Give to the heart Thy dreams have blest
The dark unconsciousness of rest!
