What I feel is that Anika will imagine Daksh as in scaring her and following her which will make protect her and to make Anika believe that Daksh is not around her, Shivaay will call the police to bring Daksh to the house to clear Anika's doubts. In between Daksh will reveal everything he did to Anika before hence making everyone esp Pinky believe in Anika and this might be a step for Pinky to accept her.
In the mean while Anika's past will also be explored because of her bad dreams.
Did I make any sense? 😆
