Leo,
Did you ever hear of about one of Jung conversations with Freud:

Freud was alarmed by Jung's letter. Jung's interest in synchronicity and the paranormal rankled the strict materialist; he condemned Jung for wallowing in what he called the "black tide of the mud of occultism." Just two years earlier, during a visit to Freud in Vienna, Jung had attempted to defend his beliefs and sparked a heated debate. Freud's skepticism remained calcified as ever, causing him to dismiss Jung's paranormal leanings, "in terms of so shallow a positivism," recalls Jung, "that I had difficulty in checking the sharp retort on the tip of my tongue." A shocking synchronistic event followed.
Jung writes in his memoirs:
While Freud was going on this way, I had a curious sensation. It was as if my diaphragm were made of iron and were becoming red-hot--a glowing vault. And at that moment there was such a loud report in the bookcase, which stood right next to us, that we both started up in alarm, fearing the thing was going to topple over on us. I said to Freud: 'There, that is an example of a so-called catalytic exteriorization phenomenon.' 'Oh come,' he exclaimed. 'That is sheer bosh.' 'It is not,' I replied. 'You are mistaken, Herr Professor. And to prove my point I now predict that in a moment there will be another such loud report! 'Sure enough, no sooner had I said the words that the same detonation went off in the bookcase. To this day I do not know what gave me this certainty. But I knew beyond all doubt that the report would come again. Freud only stared aghast at me. I do not know what was in his mind, or what his look meant. In any case, this incident aroused his distrust of me, and I had the feeling that I had done something against him. I never afterward discussed the incident with him." In formulating his synchronicity principle, Jung was influenced to a profound degree by the "new" physics of the twentieth century, which had begun to explore the possible role of consciousness in the physical world. "Physics," wrote Jung in 1946, "has demonstrated...that in the realm of atomic magnitudes objective reality presupposes an observer, and that only on this condition is a satisfactory scheme of explanation possible."
"This means," he added, "that a subjective element attaches to the physicist's world picture, and secondly that a connection necessarily exists between the psyche to be explained and the objective space-time continuum." These discoveries not only helped loosen physics from the iron grip of its materialistic world-view, but confirmed what Jung recognized intuitively: that matter and consciousness - far from operating independently of each other--are, in fact, interconnected in an essential way, functioning as complementary aspects of a unified reality.
The belief suggested by quantum theory and by reports of synchronous events - that matter and consciousness interpenetrate is, of course, far from new. ....
