Something I came across in a movie 你说它真它就真说它假 I came across this in a Chinese television show, which I would like some help to translate.

你说它真它就真，说它假它就假，它是真真假假假假真真谁也弄不明白.

The first part I do understand. It means: "If you say it is real then it is real, if you say it is fake then it is fake".

But the second part of the sentence I can't make much sense of.

Is there some brilliant mind out there that can?
你说它真它就真，说它假它就假， 它是真真假假假假真真谁也弄不明白.

You claim it's true and as truth it is. 
You declare it's faulty as falsehood is should be. 
Is it true or false, go figure!


One not so elegant translation would be 

if you say A, and I supposed to believe it as A and when you say about
the same thing but this time it is B, and I supposed to believe it is
B, so is it A or B???? what do I know???


The concept is quite similar to an old saying "to swear black is white." Or you can use the biblical reference on Mark 11:24 "Therefore I say to you, all things for which you pray and ask, believe that you have received them, and they will be granted you."  Or if you stretch this more, "Cogito ergo sum," which is the Latin philosophical proposition by René Descartes, as in English "I think, therefore I am."
