It was in the second year after we had been appointed instructors that I finally stumbled upon my 'consciousness unit' theory. Gradually I worked it out with the enthusiastic moral support of my friend, who rendered me what assistance he could.
The theory was beautiful in simplicity. It was based upon the hypothesis that a dream is an expression of one's consciousness, that it is one's second self going forth to adventure and travel. When the physical being is at rest the consciousness is released and can travel and adventure at will within certain limits.
I went one step further, however. I assumed that the consciousness actually does travel, that certain infinitesimal parts of one's brain do actually escape to visit the strange places and encounter the odd events of which one dreams.
This was taking dreams out of the psychic world to which they had formerly been relegated and placing them on a solid scientific basis.
I speak of my theory as a 'consciousness units' theory. Scott and I spoke of the units as 'consciousness cells,' although we were aware they could not possibly be cells. I thought of them as highly specialized electrons, despite the fact that it appeared ridiculous to suspect electrons of specialization.
Scott contended that a wave force, an intelligence wave, might be nearer the truth. Which of us was correct was never determined, nor did it make any difference.
As may be suspected, I never definitely arrived at undeniable proof to sustain my theory, although later developments would seem to bear it out.
Strangely, it was Scott Marston who did the most to add whatever measure of weight I could ever attach to my hypothesis.
While I was devoting my time to the abstract study of dreams, Scott was continuing with his equally baffling study of time. He confided to me that he was well satisfied with the progress he was making. At times he explained to me what he was doing, but my natural ineptitude at figures made impossible an understanding of the formidable array of formulas which he spread out before me.
I accepted as a matter of course his statement that he had finally discovered a time force, which he claimed was identical with a fourth-dimensional force. At first the force existed only in a jumble of equations, formulas, and graphs on a litter of paper, but finally we pooled our total resources and under Scott's hand a machine took shape.
