Shutter+Island.

1) "Shutter Island" subtitles: this is non diegetic because the characters don't see this. 2) At the beginning on the boat there was soft background music: this is non diegetic because the characters don't hear this music. 3) His dreams/imaginations?(When the "fake" rachel killed her kids and then asked Ted to carry them to lake): this is non diegetic because it did not actually happen in the movie? * RIGHT NOW, I am actually really confused by the movie, and am really confused about whats diegetic and what is not!* 4)When Dolores showed up in Geroge Noyce's cell 5) When Ted blew up the car, Dolores and a child stood in front of it and they couldn't be burnt 6)In the light house when he was climbing there was dramatic music playing 7) when the actual kid "rachel" + Dolores shows up and then Ted goes into this weird dream... kids drown he kills her 8) after he said "to live as a monster or die as a good man," dramatic music started to play. 9) Credits at the end.

I would argue that all of his weird dreams and imaginations can be non diegetic, because those events never really happened, even though he is aware of it (at the moment when he is dreaming!) Ted actually forgets about those stuff that happened and therefore, non diegetic because it doesn't "exist" in that world!.
