In the film Elegy from Russia by Aleksandr Sokurov, you are introduced in the film by heavy breathing and the screen is dark, sometimes showing a little light. This goes on for minutes on end and it's quite uncomfortable. After about 7 (?) minutes images appear in black and white.
Only after leaving the cinema do you realise that all the while you have been inside the body of a an old dying man, looking at images from his life, feverish dreams, flashes of memory, while simultaniously looking at images of Russia's history and - as the film calls it, the suffering of the Russian soul at the banks of the Wolga.
