Forgive the lengthy response. Some of this was to be the subject of a post I was going to make in my CIA series I no longer have time to write.

Before I get into that, wanted to say I have had several encounters with strange things over the years. One in particular though deals specifically with what is called the shadow man phenomena. Back in the mid 90's, I worked graveyard shift. The route I took was up Kolb rd, which as you near Valencia drives through Davis Monthan AFB. The road dips and the base has an overpass over the road to keep us off the base.

My wife and son were with me, as she needed the car in the morning before I got off. I watched as I was going through the base as a shadow figure ran across the road, and as my headlights closed in on it it just seemed to disappear into the concrete pylon. I always assumed the likeliest probability was it was some type of technology the AFB was using, but who really knows?

Now onto the part I was to write about. I studied Castenedas work for decades. It was the most complete work I have ever written on dissecting perception and reality. Everything from hunting to stalking to you name it. Examining motivations, moods and many facets of reality (with practical exercises) for shifting things. The basic tenet being that sorcery is an act of perception, something so basic anyone with the proper intent can perform. Towards the end of his writings, his work took on a darker nature, one that felt off to me. It dealt with these beings you write of in depth, his last major work "Being In Dreaming" solely focused on these beings and their usefulness to humans. I felt the pure evil of it all then, but still remained ignorant of a lot until years later.

Through research I discovered the CIA has a penchant for the occult, and creating different cults. I won't repeat the things I already wrote about, but in my research (that I was waiting to write and now wont be here) was a claim by Castenedas ex wife in which she said that before he wrote these books, he had worked as an assassin for the CIA.

Now the question to be asked, is it a hoax using mind control techniques or is the CIA itself the agency that such beings enforce their will on the planet? To this I have no answer.
