dream time

I'm a little stuck... Click here to teach me more about this clue!

'a golden age' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?

'meter maid's wafted' is the wordplay.
'wafted' is an anagram indicator (I've seen 'wafting' mean this).
'meter'+'maid'='metermaid'
'metermaid' anagrammed gives 'DREAM TIME'.

'into' acts as a link.

Can you help me to learn more?

(Another definition for dream time that I've seen is " Aboriginals' golden age".)

I've seen this clue in The Telegraph.
