I've read, seen, and taught The Tempest, but these lines never stood out to me till I came across them yesterday in another book I'm reading:

     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.
