You know your head is fast asleep when you can't tell whether you are listening to Polish or Russian. Both just sound the same.
Today's "lullaby" (listening but not watching while all curled up under a couple of blankets) is the film Katyn by Andrzej Wajda (hence the mix of Polish and Russian. They do some shouting in German as well). Listening to it might not be the most clever thing to do, as it will probably cause nightmares for days to come, but it tells the story of a very important piece of European history and I believe that it is something that one should be aware of.
