Thats a good explanation mappi. I did understand it in the first viewing but did not find anything impressive in the way these 'layers' were depicted. Just to show that she started hallucinating after reading a book on Burma, KVA made 30 mins of beaten-to-death love story shot in Burma, which doesn't have anything to do with the 2 other stories that follow? He could have cut it short like Ilamaran segment. The only reason why this was shown is probably to make us suspect Radhakrishnan, for most part of the movie.
Heroine consults a psychiatrist --> explains her dreams which are actually fabricated, based on what she heard and read --> Karthik get the inputs from the doc and makes video games which sell across the world --> Still heroine/her friends, relatives never come to know that the games are based on her life/lives???
And these employees take energy shots, prescribed by in-house doctor!!!
