The Early Sessions, Book 3

"Every subconscious personality then would see and hear the same dream, as many persons may watch the same movie; and as each person in a theater interprets the symbolism of the drama differently, so does each layer of the subconscious interpret differently the same elements of one dream. The I who dreams, who is aware of motion, action and participation in a dream, this I is of course the inner self, focused momentarily upon the particular subconscious layer at which the dream is originated."
