But let me be more explicit.

The commonest race memory we have is the falling-through-space dream. This other-personality is very vague. About the only memory it has is that of falling. But many of us have sharper, more distinct other-personalities. Many of us have the flying dream, the pursuing-monster dream, color dreams, suffocation dreams, and the reptile and vermin dreams. In short, while this other-personality is vestigial in all of us, in some of us it is almost obliterated, while in others of us it is more pronounced. Some of us have stronger and completer race memories than others.

It is all a question of varying degree of possession of the other-personality. In myself, the degree of possession is enormous. My other-personality is almost equal in power with my own personality. And in this matter I am, as I said, a freak—a freak of heredity.

I do believe that it is the possession of this other-personality—but not so strong a one as mine—that has in some few others given rise to belief in personal reincarnation experiences. It is very plausible to such people, a most convincing hypothesis. When they have visions of scenes they have never seen in the flesh, memories of acts and events dating back in time, the simplest explanation is that they have lived before.

But they make the mistake of ignoring their own duality. They do not recognize their other-personality. They think it is their own personality, that they have only one personality; and from such a premise they can conclude only that they have lived previous lives.

But they are wrong. It is not reincarnation. I have visions of myself roaming through the forests of the Younger World; and yet it is not myself that I see but one that is only remotely a part of me, as my father and my grandfather are parts of me less remote. This other-self of mine is an ancestor, a progenitor of my progenitors in the early line of my race, himself the progeny of a line that long before his time developed fingers and toes and climbed up into the trees.
