We are such stuff as dreams are made on ... The Tempest, Act IV, Scene I
by William Shakespeare

Our revels are now ended. These our actors,

As I foretold you, were all spirits and

Are melted into air, into thin air;

And like the baseless fabric of this vision,

The cloud-capp’d towers, the gorgeous palaces,

The solemn temples, the great globe itself,

Yea all which it inherit, shall dissolve

And like this insubstantial pageant faded,

Leave not a rack behind. We are such stuff

As dreams are made on, and our little life

Is rounded in a sleep.
