Sorry. Another request for advice.
In comics, there are those 'thought bubbles'. Are there are any such tricks in cinematography? As a child, I remember getting confused with films like 'Billy liar' and 'If'.
'Dreaming/asleep' seems to be easier as the film can show a sleeping person and use some focusing transition and jingly jangly sleep music; and then enter the dream world.
But 'daydreaming' seems to be more difficult to show. Inevitably, I can always use a thought bubble mask; but was wondering if anyone knew of any more interesting examples.
