Reveries (6)
I believe the answer is:
dreams
'reveries' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dreams that I've seen before include "Thoughts and visions during sleep" , "'''We are such stuff as ... are made on'' The Tempest (6)'" , "Imaginings" , "Fantasies; fantasises" , "'We are such stuff / As dreams are made on' (The Tempest)" .)
