As I tried to accept my fate, an even lower portion of my brain began to transmit more visions and information. I was "told" that this new material was being presented to me because I was dying and therefore "safe" to receive these revelations. These were the secrets reserved for the dying and the dead, I was informed.
I could only very dimly perceive the givers of these thoughts: giant reptilian creatures reposing sluggishly at the lowermost depths of the back of my brain, where it met the top of the spinal column. I could only vaguely see them in what seemed to be gloomy, dark depths. Then they projected a visual scene in front of me.
They explained to me in a kind of thought language that they were fleeing from something out in space. They had come to the planet Earth to escape their enemy. The creatures then showed me how they had created life on the planet in order to hide within the multitudinous forms and thus disguise their presence. Before me, the magnificence of plant and animal creation and speciation—hundreds of millions of years of activity—took place on a scale and with a vividness impossible to describe. I learned that the dragon-like creatures were thus inside of all forms of life, including man. They were the true masters of humanity and the entire planet, they told me. We humans were but the receptacles and servants of these creatures. For this reason they could speak to me from within myself.
