He later would compare this period of his life — this “confrontation with the unconscious,” as he called it — to a mescaline experiment. He described his visions as coming in an “incessant stream.” He likened them to rocks falling on his head, to thunderstorms, to molten lava. “I often had to cling to the table,” he recalled, “so as not to fall apart.”
Had he been a psychiatric patient, Jung might well have been told he had a nervous disorder and encouraged to ignore the circus going on in his head. But as a psychiatrist, and one with a decidedly maverick streak, he tried instead to tear down the wall between his rational self and his psyche. For about six years, Jung worked to prevent his conscious mind from blocking out what his unconscious mind wanted to show him. Between appointments with patients, after dinner with his wife and children, whenever there was a spare hour or two, Jung sat in a book-lined office on the second floor of his home and actually induced hallucinations
— what he called “active imaginations.” “In order to grasp the fantasies which were stirring in me ‘underground,’ ” Jung wrote later in his book “Memories, Dreams, Reflections,” “I knew that I had to let myself plummet down into them.” He found himself in a liminal place, as full of creative abundance as it was of potential ruin, believing it to be the same borderlands traveled by both lunatics and great artists.
