Remember Chapter 13 of the Fire Control manual? Don't approach a landed "alien" craft. There's evidence for possible malevolence.
My own group of, no doubt severely misunderstood, "memories" suggests to me a mixed bag. There are a couple of Dreams, and memory mixes, portraying darkness, there is just no doubt about it! In addition to this there is the beginning of the experience via the Bahamas, where I clearly reacted as if I thought they were evil.
But there are other memories, and experiences, that would seem to point toward the angelic. More of a gentile overseer type of persona.
One strong "memory" I've always had was as a young boy dealing with being shown a polluted beach...not unlike what we are witnessing in the Gulf of Mexico right now, and being scolded by one of these "beings"...severely!!!...as if I had anything to do with it...especially at 5, or 6...whatever age I was...but it REALLY seemed that the being was serious...and seriously angry! I remember pleading..."what do you mean?...I didn't do anything!!"...etc.
I don't know. Sometimes I think I've got a handle on it, but most times I can only shrug. I read Strieber, and clicked when he said "cinnamon, and wet cardboard", sent him a thank You email, and went on with my life.
Then I have a rash of sightings which I report to the National UFO Reporting Center. These evolve into a series of sightings of silvery spheres...which always show up white, or black in my photographs. They also seem to be interested in the sudden escalation of persistant contrails...as they are seen, and photographed in, and around them.
This would all seem to lend credence to the multiple groups, with multiple agendas approach to it all. Still, I don't know for sure what they are interested in, but I do know that "they" are very real...who, or whatever they are.
