I've often dealt with evil spirits trying to attack me many times in my life. They sometimes manifest "physically", in that they affect physical objects like "auto-kinesis", with other witnesses.
I've also encountered beings that apparently look like the mainstream aliens when I was a child. I never saw their craft but somehow, they made our house shake in the middle of our neighborhood late at night and we heard a loud noise that sounded like a big, powerful tornado. My sister saw what was happening as well.
The most curious thing, we heard the neighbor's dogs barking but nobody else awoke. Not the neighbors, except their dogs. Not even our parents in the next room as if this being targeted me and my sister specifically.
I felt strong "negative energy" coming from this being. I also felt the same thing when I encounter evil spirits.
When I encountered God in dreams or probably an angel as a very young child, I felt a different but similar energy. But this energy is way more powerful and overwhelming. It wasn't a pleasant feeling. It was scary. It probably feels like a billion volts of electricity surging through your mind. If it can be described. Not exactly like being "showered by good and pleasant feelings of love" as modern Christians describe it. I think it's more like how many characters in the Bible describe meeting the Lord or an angel. They were scared.
My experiences still does not establish a fact that aliens and fallen angels are the same. Eventually, I evolved to "feed" on their energies and use their energy against them to cast them out. It's all instinctive. From many attacks throughout my life, my brain just learned to put up defenses against it. And I'm still 100% human being.
My point is that it may be entirely possible for a physical being to advance in technology or evolve to a point, they can manipulate spiritual energies. The spiritual dimension could be the pinnacle of technological and biological evolution. Aliens could be harnessing untold energies from the spiritual dimension through technology or certain evolved abilities but doesn't make them a fallen angel or angel. But still entirely possible a biological alien might be working with fallen angels or even with Lord.
It's really not that easy to tell apart which ones are good and which ones are bad. We've been living a lie our whole lives. Most people really have the wrong concept of what is good and what is evil that's why when people try to solve a problem, the consequences are worse than the problem they're trying to solve in the first place.
The question I would have about that is - if you have never been actively involved in the occult at any stage of your life, have anyone related or close to you involved in the occult?
It is interesting that although UFOs have crashed into the earth, they have discovered the craters, but no trace of any bodies or debris. If an aircraft had crashed, there would be debris all over the place. Also, with the objects moving at high speed through the atmosphere, there is no sign of sonic booms or surface heat causing a glow. When the space shuttle entered the atmosphere, a bright red glow appeared at its front through atmospheric tension.
What this shows is that these objects don't contain any biological beings, and the UFOs themselves are not physical. Therefore they don't originate in our space time dimension. They enter from a dimension outside it. We know that angelic beings can come from outside our space time dimension, but we can't go there. We also know that righteous angels are there to support the redemption of mankind, and so the only alternative is that they have to be unrighteous spiritual beings.
The research shows that many who have had close encounters with UFOs, have had terrifying nightmares as a result. This shows that there is a distinct connection between UFOs and the occult.
Now, having said that, research has shown that 99% of UFO sightings have been either hoaxes, planet Venus, star groups rising over the horizon, or reflected lights from buildings. But there is a 1% which are real, and it is these that we are talking about that people have seen and encountered.
Close Encounter 1 is contact with a UFO within 500 metres.
Close Encounter 2 is contact involving a message
Close Encounter 3 involves actual beings.
Close Encounter 4 results in damage, injury and death.
These encounter levels are the result of the conclusions of the foremost UFO researchers in the scientific community.
You don't have to believe me. You can do you own research to establish whether what I am saying has value.
