The Dreamer (1961)

Just like millions of others, the man wakes up and gets up. Work awaits him. But while he gets ready, he can't help getting lost in daydreams. He pictures himself in turn as a sports champion, an opera singer, a general, an orchestra conductor, a lover - All that makes him very happy but also - very tired. Now he needs a rest. The only thing to do is to go back to bed.
