This whole creation is essentially subjective, and the dream is the theater where the dreamer is at once scene, actor, prompter, stage manager, author, audience, and critic.

Jung is emphasizing the radical interiority of dream experience: in dreams, the psyche generates not only the “story” but also every role within it. The dreamer is simultaneously the world depicted (scene), the figures who act (actor), the guiding impulses that cue events (prompter), the organizing intelligence that shapes the sequence (stage manager/author), and the observing consciousness that reacts to it (audience/critic). Read in a Jungian key, this supports the idea that dream images are expressions of the dreamer’s own psychic contents—often autonomous complexes or archetypal patterns—presented in dramatized form. The line underscores why Jung treats dreams as self-revelations of the psyche rather than messages imposed from outside.
