I do not think Pre dreaming about Anurag is wrong or incorrect anywhere ....
It’s her subconscious mind that dream about him .... which stills Love him and that is happening because she still has not got Closure with him .
That confrontation with Anurag on that day would have given her that Closure and that never happened .....so her subconscious mind somewhere is still keeping that Umeed Alive .....
You can put millions of facade , make your believe what you want to believe but unless that last ray of hope is still alive ...... you’ll unknowingly try seeking answers ....
Prerna on that day went through series of betrayal , yet she kept believing that Anurag can’t do this ..... but He does ..... and she never got the reason why he did that .... and that is what has made crazy these 8 years ....she has extreme Love as well as Extreme Hate for him ....
The confrontation will help her choose the one side ...
