There is a chinese idiom called 想入非非:

to indulge in fantasy

Is there is an english idiom that is similar to this?

Searching gave me this strange "idiom":

allow one's fancy to run wild

right and wrong

wishful thinking

indulge in flights of fancy (flights = 量词)

Who has been putting ideas in his head?

William Shakespeare’s The Tempest in Act IV, Scene 1.

Prospero: You do look, my son, in a moved sort,
As if you were dismay’d: be cheerful, sir.
Our revels now are ended. These our actors,
As I foretold you, were all spirits and
Are melted into air, into thin air:
And, like the baseless fabric of this vision,
The cloud-capp’d towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Ye all which it inherit, shall dissolve
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on, and our little life
Is rounded with a sleep.

Just thought I'd try and squeeze 想入非非 into Prospero's mouth!

We are such stuff as dreams are made on, and our little life is rounded with a sleep.

Many websites show that this chinese idiom is similar to the one above:



additionally, according to Sir TL Tang (a Hong Kong professor),

「想入非非」(是胡思亂想),英文是to allow the fancy to run wild。不過這些翻譯不如原文般用字精練和生動


as an example• we will allow our fancy to run wild •( 我們胡思亂想, 想入非非) from this google book
