Fantasies? Daughter has lots (6)
I believe the answer is:
dreams
'fantasies?' is the definition.
(dream is a kind of fantasy)
'daughter has lots' is the wordplay.
'daughter' becomes 'd'.
'has' is a charade indicator (letters next to each other).
'lots' becomes 'reams' (I have seen 'Lots of paper ' mean 'reams' so perhaps 'lots' could also mean 'reams').
'd'+'reams'='DREAMS'
(Other definitions for dreams that I've seen before include "Fantasies; fantasises" , "Thoughts and visions during sleep" , "Imaginings" , "'''We are such stuff as ... are made on'' The Tempest (6)'" , "'We are such stuff / As dreams are made on' (The Tempest)" .)
