Here’s the deal with theta: it’s a different kind of knowing than beta. Beta is a crisp, oh-I-just-cogitated-this-thought. But experience in theta is knowing. Theta hits you in a total, murky, deep-but-diffuse way.
Your everyday beta knowing feels like, hey here’s a knowledge I found, let us rotate and consider this sparkling, clearly-defined concept. Theta’s not like that. Theta knowing extends with no clear edge, even implicating you, whether you want it or not you’re part of the knowledge like some inseparable field and wave.
If I were going to study psychic shit, my money would be on theta providing access to a buffet of non-local information. Like weird, action-at-a-distance, outside of conventional time and space info. This is a different kind of knowledge, and you can’t approach it like regular, daylight, yes-no questions, because it’s not structured that way.
