Thnx for sharing the info Jammy, but I seriously doubt that this sequence is going be taking place anywhere other than the land of the asleep.....
Jassi slapping Armaan is something that does not fit with Jassi's character (granted that so do not a hundered other things)....personally I can see Jassi slapping Armaan immediately after reading the letter, when she hasnt had time to calm herself.....but after talking to Nandanii and having a heart to heart with Nandu, and not to forget the time that has lapsed between the incident and "slapping Armaan" sequence, this action just does not ring true....
