When I go to "Night School", (which, BTW, is open to every human on Earth) I never look for intel or predictions. I always try and come back with strategic wisdom. You can argue with intel, it's harder to argue with wisdom. I will see a vague idea form like a thought/emotion form, and get an idea for google search terms. Next day I check, and there's normally something on google."Oblong trapezoids"
I was really thinking about this on a personal level, in terms of using my own judgement. I'm impressed that you have already nearly designed a new system to ferret out the shammers.
Action requires judgement. Personally, I use knowledge, experience, instincts, emotions, logic and analysis, I may be leaving something out. As I've said before, my instincts carry heavy weight and can trump some or all of the other parts of judgement.
Obviously there's no way for me to offer up instincts as any kind of proof. Some things just can't be proven. I can't prove I had a particular dream but it may change my life for good.
A meta-analysis of disclosers or predictors could give a kind of template to do a quick assessment of the latest insider. Like being able to make a quick profile.
Plus, they never lecture you, it's more like a co-creation or heart-mind to heart-mind where they help you access you inner self or ideas.
Who knows where my ideas come from?
Maybe my subconscious, or the heart of humanity. I just call it "pulling ideas out of the ether." Dreamers, artists and inventors have been doing it for centuries. In the next meditation, you can ask for help executing the idea, or there is assistance in avoiding disagreements with the team, or unblocking emotionally. Last, you don't need to astral project up, as there can be trap layer there. It is easier to go deep inside the brain, heart, or other chakra.
In Indonesia, they call this place "The Other Heaven", my teacher went there and started to learn French. You don't have to remember anything, and there probably aren't lecture rooms and chairs, not on the 5th dimension and above anyway. It's more about writing the first idea that comes when you wake up, and writing it quick before doubts, anxiety and murky emotions creep in.
As the etheric plane disintegrates, this process will get easier and easier.
We are being helped, and the door is open...
