Samuel Taylor Coleridge
Something Childish, but very Natural. Written in Germany
If I had but two little wings
 And were a little feathery bird,
   To you I'd fly, my dear!
But thoughts like these are idle things,
     And I stay here.
But in my sleep to you I fly:
 I'm always with you in my sleep!
   The world is all one's own.
But then one wakes, and where am I?
     All, all alone.
Sleep stays not, though a monarch bids:
 So I love to wake ere break of day:
   For though my sleep be gone,
Yet while 'tis dark, one shuts one's lids,
     And still dreams on.
