Blake's Mirror

I dreamt a dream! what can it mean?
And that I was a maiden Queen,
Guarded by an Angel mild:
Witless woe was ne'er beguil'd! 

And I wept both night and day,
And he wip'd my tears away,
And I wept both day and night,
And hid from him my heart's delight.

So he took his wings and fled;
Then the morn blush'd rosy red;
I dried my tears, and arm'd my fears
With ten thousand shields and spears.

Soon my Angel came again:
I was arm'd, he came in vain;
For the time of youth was fled,
And grey hairs were on my head.

Little Fly,
Thy summer's play
My thoughtless hand
Has brush'd away.

Am not I
A fly like thee?
Or art not thou
A man like me?

For I dance
And drink & sing:
Till some blind hand 
Shall brush my wing.

If thought is life
And strength & breath
And the want 
Of thought is death;

Then am I
A happy fly,
If I live,
Or if I die.

Memory, hither come
  And tune your merry notes;
And while upon the wind
  Your music floats,

I'll pore upon the stream,
  Where sighing lovers dream,
And fish for fancies as they pass
  Within the watery glass.

I'll drink of the clear stream,
  And hear the linnet's song,
And there I'll lie and dream
  The day along;

And when night comes I'll go
  To places fit for woe,
Walking along the darkened valley,
  With silent melancholy.
