Run over the best possible dream (6)

I believe the answer is:

revery

'dream' is the definition.
(I know that revery is a type of dream)

'run over the best possible' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'over' says to put letters next to each other.
'the best possible' becomes 'every' (I've seen this before).
'r'+'every'='REVERY'

I've seen this clue in The Times.
