Also interesting about this book is that the patient whose dreams are being analyzed in the second section is the physicist Wolfgang Pauli, who would go on to collaborate with Jung on such ideas as the acausal connecting principle of synchronicity. The dreams are interpreted as a series to elucidate the meanings of recurring motifs and symbols, with the series culminating in the vision of a 'world clock', which is actually several clocks on different planes operating on different scales and colours as a symbol of Pauli's unconscious apprehension of some grand cosmic order. Three of the best of these dreams were also mentioned by Jung in his Terry lectures "Psychology of Religion".
