The Science of Sleep

Went to the movie last Friday and watched that movie. It's about a Franco-Mexican guy who gets back to Paris. He's a day-dreamer, an artist who falls in love with his neighbour. His boring day-job (where he seldom shows up in time, or at all) gives him nightmares. He's a bit lost in Paris. Surprisingly, he can't speak french (although it seems he lived in Paris as a kid).
People in the movie speak all kinds of languages, including french and Spanish, mostly English. That makes for an interesting mix.
The complete lack of distance between the main character and his neighbour is a bit strange, they get friendly way too easily. Yet it made me a bit homesick... The only neighbour I met in my building is a ridiculously beautiful woman (must be 30-something?) who lives upstairs. Haven't met her for two weeks, by the way. It feels cold here.
