"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."
Caliban -The Tempest act III
