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 in him getting a parallel in his dream, the distinction between reality & 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.
