Pay attention to the "logic" or the rationale. So according to Sedala, not all the phenomena can be catagorized as "demonic". Some of the experiences are not negative. Quite the opposite. Some can be considered "very good". And the criteria for the event to be called "very good", is when a person encounters a craft/being/some phenomenon, and they feel "euphoric" afterwards. And if an electronic equipment is present, it's possible to see all kind of deviations when this "influence" is happening.
He also shared a story about a cave in a basin. People took some crystals from the cave and brought them home. And it produced a lot of chaotic activity. Apparitions, nightmares, all kind of bad stuff. They brought the crystals back to the cave, and when they came back home, everything returned to normal and they felt euphoric. They started feeling much much better than their regular "base line".
Dr. Jim Segala said, that whatever it was "rewarded" them for good behavior, and that it is an example of the experience being "positive".
We can see the above as an example of how tricky it's going to be, and how many people won't look or think beyond the "skin deep" level.
I think that this is a lesson we've been learning for quite some time and part of why learning about psychopaths and dark personalities is so important and a big part of The Wave series. That's exactly what we learn to see when we learn about this types, that they can present as very positive, charming, beautiful and even helpful people but in reality they are just lying, manipulating and using everyone for their own agenda. I think most people still tend to think that bad people are just ash*** and tend to base their judgment on how other people make them feel and how they look superficially. It's such a hard topic that even experts on the field can't agree on it completely and some can still fool people who are very well trained to detect them. The more we learn about them, the more we can train ourselves to see the unseen too, IMO.
