In the precap it was shown that dadi discloses to everyone in the house that Razia herself told her that she got Dilshad almost killed.
Well I think Razia must be terrified about revealing the truth to Dadi and was dreaming whatever was shown in the precap.
As much as I have understood dadi,she won't disclose the truth without any proof.She is quite wise.If she had to disclose the truth,she would have told about the tv news then and there itself.But she didn't.
So, my instincts say that the precap is going to be a dream of Razia.
Dadi may also dream it and then she may see that noone believes her.This dream might also stop her from going ahead and revealing the truth.
Well these are my views guys.
What do you think?
