The Dream Book of Self-Knowledge
- animals speaking with a human voice: if the dreamer understands them or communicates with them, then he has understood the instinctual traits related to the individual animals.
- a talking bird: if the dreamer understands it, then this scene proves that he has fully understood the inner importance of the symbol of a bird (or of another species) in the unconscious and in dreams.
- a horse speaking in a human language: a very important dream since the dreamer has found a sincere relationship to the transitional symbol of the horse (instincts-emotions) enabling him to understand and control the instinctual component for the good of emotions.
- speaking with a snake: important familiarization with the symbol leads to an understanding of the snake's positive role in the unconscious (see Snake).
