A succession of outlandish numbers in dream about money? (10)
I believe the answer is:
eurovision
'a succession of outlandish numbers' is the definition.
I can't judge whether this defines the answer.
'dream about money?' is the wordplay.
'dream' becomes 'vision' (I've seen this before).
'about' means one lot of letters go next to another.
'money?' becomes 'euro' (currency of the Eurozone).
'vision' put after 'euro' is 'EUROVISION'.
'in' is the link.
Can you help me to learn more?
(Other definitions for eurovision that I've seen before include "TV network" , "contest?" .)
