What Is Real?

As the title suggests, the film invokes a conversation about the blurring of lines between reality and make-belief. Two people, a woman and her doctor, are having a conversation about a person, a hallucination that seems to overpower her life. She shares with him the intimacy and comfort, one she finds unable to replicate in any other relationship of hers, explaining precisely why she clings to this non-existent companion of hers.

Now that the premise of the film has been established, an unexpected shock awaits the viewer. And it is in this development that the narrative justifies its title and the question it has pivoted itself on all along.
