Some of us are thinking it's a dream while few others are thinking it was reality.
If it was reality, I am very happy that Milind recognized his Prachi instantly. He didn't buy her lie that she was Panchi even for a second. Though he seemed to have known that she has been faking a life in the DG family, he trusted that she still loves him and him only. He wanted her back and that's all mattered to him "meri Patni Prachi"- that's the possessiveness of Milind Mishra. I am so glad to see him back like this.
If it was a dream, it has got to be Prachi's dream. I am glad that at least in her dream Prachi appreciated that all Milind wants is her and he trusts her. She knows she can't convince him that she is some one else and unlike her, he hasn't assumed she would have moved on with some else.
I want it to be a reality- because if it was a dream, the opposite will happen in reality. I don't want Prachi to make Milind buy her lie.
I personally feel it was too long a dream to be a dream. It involved too many events to be a dream. I hope Prachi wasn't dreaming.
And I don't want Prachi to lie in front of God (as the preview showed she was asked to speak the truth with her hand on the "diya"). I hope at least God won't let her lie, for Milind's sake.
