in Nubibus

"O, it is pleasant, with a heart at ease,
  Just after sunset, or by moonlight skies,
To make the shifting clouds be what you please,
  Or let the easily persuaded eyes
Own each quaint likeness issuing from the mould        
  Of a friend’s fancy; or with head bent low,
And cheek aslant, see rivers flow of gold
  ’Twixt crimson banks; and then, a traveller, go
From mount to mount, through Cloudland, gorgeous land!...." 

~ Fancy in Nubibus, Samuel Taylor Coleridge.
