A monster reflects

A Caliban speech from The Tempest:

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.
