We have not often the chance to see both famous psycho analysts Freud and Jung attending a real psycho analysis session, where they can observe what became of the science they invented. This film offers that rare opportunity, even to the extent that we see these two learned experts fighting over the approach taken.
In fact, Freud and Jung are just pictures hanging on the wall. Not limited by their form they cover their ears, or applaud what is being said by the resident psychiatrist. Some of the time they even strike or kick each other, resulting in broken glass and ultimately both falling on the floor.
Things like this, and many other "impossible" things, can be turned into reality when integrating live figures with an animated decor. The director makes his appearance at the start of the film, to explain this uncommon setting as being inevitable, not being able to raise enough cash for a "real" film. Given what we know about this director, we easily pick this up as a joke, because of his established fame in delivering animated pictures.
The story gets complicated where reality starts getting mixed with dreams, but not too difficult to follow. Missing one or two clues is not the end of this particular world, where humor and satire go along hand in hand. That is especially the case when psychiatric practices are ridiculed, for instance the frivolous attempts made to explain the dreams of the main characters in this story.
