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.
William Shakespeare
