Alienmind and Undermind--Is there a difference?

In the process of reading Opening Minds aloud, in preparation for the upcoming audio version of the book, I was struck by the encounters of "Bob" and several others mentioned in the text, who reported alien contact of one form or another. Some individuals reported seeing 7-foot tall reptoids near them. Others reported having different varieties of sexual encounters. Looking back at these reports several years after writing about them I began to wonder: What causes people to have these weird experiences? Since I don't think that any of them are making it up, I can only assume that our minds are much more mysterious than we care to admit. Yes, on the surface it seems that science can come up with a fairly coherent explanation of what our minds do from moment to moment. But at another level, there is a degree of pure strangeness to the whole affair. Perhaps there is a continuum which at one level includes ordinary waking-state experience, and at the other, a connection to other life forms and broader universal consciousness. Since we don't have a lot of formal training in dealing with the later, it may across as feeling as if it were distinctly "other." Thus, we project those seemingly bizarre feelings and sensations outside of ourselves as "aliens." But in another way, the aliens are portions of our own undermind, that we haven't integrated very thoroughly in our daily experience. They emerge from our consciousness, and then appear as if they came from "out there." In this sense, the alien mind and our undermind form a continuum and to some extent are the same thing.
