From The Tempest

CALIBAN: Be not afeard; the isle is full of noises,
Sounds and sweet airs, that give delight, and hurt not.
Sometimes a thousand twangling instruments
Will hum about mine ears; and sometimes voices,
That, if I then had wak'd after a long sleep,
Will make me sleep again: and then, in dreaming,
The clouds methought would open and show riches
Ready to drop upon me; that, when I wak'd
I cried to dream again.

— "The Tempest," by William Shakespeare (Act III Scene II)
