“The conscious mind, combined with the subconscious, not only wants to finish the picture, but decides sometimes to eliminate a detail which does not belong to what it has guessed should be there. For example, I will discuss the drawings which have been given as Figures 35, 35a, in this book. I ‘visioned’ what looked like a figure 5, except that at the top where there should be a small vertical line projecting toward the right, there was a flare of very long lines converging at one end. I consciously decided that the long lines were an exaggeration and multiplication of what should properly be at the top of a five, and that I should not accept them. Here was conscious mind making a false decision. But by obeying the rules I had laid down in advance, I was saved from this error of consciousness. I closed my eyes, gave a call for the true picture, and the lines appeared again, so I included them in my drawing. When I opened the envelope and looked at the picture inside, it was an oil derrick. So the flare of long lines was the real thing, while the figure 5 was the interloper—at least, so I now consciously decided. I thought that the figure 5 and the flare of lines were entirely separate mental images, one following the other so rapidly that they appeared to belong together. “But again my conscious decision was in error. Several hours later, after I had put the whole matter out of my mind and had been attending to household duties, I suddenly remembered the paper jacket of a German edition of my husband’s novel, ‘Oil,’ which was on a shelf in the next room to the one in which I had made my experiments. Why did I suddenly remember this book? I had not noticed it for a long time—its jacket drawings were out of sight, as the book was wedged between many others on the book shelves in an inconspicuous place in the room. On one side of the jacket of this book was a picture of three oil derricks; on the other side was a large dollar mark, almost covering one entire side of the book. I had seen this jacket, had indeed taken special notice of it, at the time of its arrival from Germany. So here seems to have been a clear case of the subconscious mind at work during my experiment, adding to my true vision of an oil derrick, the subconsciously remembered dollar mark which looked like a figure 5, partly hidden by the oil derrick in my vision. Here was a grand mix-up of the false guesses of consciousness and subconsciousness, and the true presentations from the ‘deep mind.’
