Fantasise about barricade put round (5)
I believe the answer is:
dream
'fantasise' is the definition.
(I've seen this before)
'about barricade put round' is the wordplay.
'about' becomes 'rea' (I've seen this in other clues).
'barricade put' becomes 'dm' (I can't explain this - if you can you should believe this answer much more).
'round' means one lot of letters goes inside another.
'rea' placed inside 'dm' is 'DREAM'.
Can you help me to learn more?
(Other definitions for dream that I've seen before include "Fantastic but vain hope" , "Think vaguely" , "Vision, fantasy" , "Reverie or nightmare" , "Aspire" .)
