It's not Shakespeare but it's still pretty clever!
"When I in dreams behold thy fairest shade
Whose shade in dreams doth wake the sleeping morn
The daytime shadow of my love betray’d
Lends hideous night to dreaming’s faded form
Were painted frowns to gild mere false rebuff
Then shoulds’t my heart be patient as the sands
For nature’s smile is ornament enough
When thy gold lips unloose their drooping bands
As clouds occlude the globe’s enshrouded fears
Which can by no astron’my be assail’d
Thus, thyne appearance tears in atmospheres
No fond perceptions nor no gaze unveils
Disperse the clouds which banish light from thee
For no tears be true, until we truly see"
