Dozer's head with fantastic realm inside? That's it! (9)
I believe the answer is:
dreamland
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'dozer's head with fantastic realm inside?' is the wordplay.
'head' says to take the initial letters.
'with' becomes 'and'.
'fantastic' is an anagram indicator (a fantastic or improbable ordering of the letters).
'inside?' means one lot of letters goes inside another.
The initial letter of 'dozer' is 'd'.
'realm' anagrammed gives 'reaml'.
'd'+'and'='dand'
'dand' going around 'reaml' is 'DREAMLAND'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for dreamland that I've seen before include "Utopia" , "Nod, perhaps" , "Sleep; ideal world" .)
