"The Invisible Guest" primarily refers to Mary Watkins' psychological work on imaginal dialogues regarding the "autonomy of the imaginal other", or the 2016 Spanish thriller film ( Contratiempo ) known for its complex, layered narrative. The concept also extends to literary works like H.G. Wells' The Invisible Man or a social psychology theory regarding perceived judgment.
