Read my sad unhappy fantasies (9)
I believe the answer is:
daydreams
'fantasies' is the definition.
(I've seen this in another clue)
'read my sad unhappy' is the wordplay.
'unhappy' indicates anagramming the letters.
'read'+'my'+'sad'='readmysad'
'readmysad' anagrammed gives 'DAYDREAMS'.
(Other definitions for daydreams that I've seen before include "hopeful aspirations?" , "Fantasise while awake" , "Idly imagines" , "Reveries" .)
