Consider the phenomena of cattle mutilations - it still goes on but has long since ceased to be reported on by MSM. Then consider the phenomena of vanishing people - people that have completely vanished with no physical evidence found to explain what has happened to them. Lots of these take place in remote aspects of national parks and federal lands. There is a guy that writes books on this exact subject and gets widely interviewed about it. Really sobering to listen to the cases that he has researched. These two phenomena taken together could be indicators of some sort of non-human intervention that is not at all what one describe as being of friendly demeanor. Whether ET or interdimensional? Who knows. I've had a direct encounter with the latter kind of evil and it emitted a field of malevelance that was as palpable as some sort of force field. When it went away, that evil field it projected went away too like light switch being flipped. It didn't seem to have that great of a capacity to interact with our physical world, so I'm not inclined that the kind of entity I had a run in with is behind cattle mutilations and human abject dissapearances.
