Enakkul Oruvan (2015)

A man suffering from insomnia gets introduced to pills that allow him to cultivate and experience lucid dreams that could continue with interruptions too. With each real-life character that has caused an impact on him getting a parallel in his dream, the distinction between reality and dream thins out and that consumes him. The final act on how he gets out of it brings the curtains down with a wonderful little perspective brought to note.
