First of all, it’s not ‘Spring, Summer, Fall, Winter… and Spring’.
I watched it somewhere around 2008/9, but on TV, so I guess it’s little older then that. I remember it being Asian movie (Japanese possibly), where the protagonist has to go through all seasons of the year, but they are embodied – for example, autumn is represented as a gypsy woman. For summer I remember that while he was sleeping, his dreams got ‘projected’ onto the wall. I think the story ends in winter: it snows and he gets covered with snowflakes.
