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 sometime voices
That, if I then had waked after 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 waked
I cried to dream again.
– Shakespeare’s The Tempest, III, ii
