It seems like these demonic beings appear to non-Christians, unbaptized Christians or those who are in serious sin, one of which could be a good person but unbelief. I've read accounts where people scared them off by invoking the name of Jesus Christ.
Last night was totally weird on C2C, couldn't sleep so listened to this account of some dragon fly drones, a message being impressed in the mind of the witness, the witness once he had typed the message on his computer (downloaded), it was erased from his mind.
Then he was led to a book from the library he found on a table and checked it out, copyrighted in 1962, titled "Ancient Greek Gods and Lore Revisited" by Fredrico Ionnides. The man, was being interviewed by Linda Moulton Howe, was visited at work by two high govt types that demanded the book for "national security" reasons. His boss who knew a little of his adventures ordered him to turn it over, figured he had to because of the Patriot Act.
Linda made an appeal for a copy of that book. I can't find one and don't know if it exists.
The whole thing could be made up, but you can google or search YT and find the segments of last night's show. The man (Ted Connors) also mentioned having the tree bark analyzed that the drone was hiding behind when he first spotted it. Said it contained Paladium. That's a very rare earth metal.

There have been umpteen variations of this theme ever since that Betty and Barney Hill? case and others, phenomena seem more frequent now.
The question “are they here” is COMPLETELY different than “is it possible that they exist”.
Interactions with non human intelligences is outside my experience but the possibility is within my world view. God deliver us from evil.
