Once I wake up knowing how to do a math problem that I puzzled hours over the night before. Once I made a mistake in posting as a lettershop operator, and (it was a slow night), I sat there for a couple of hours trying to figure out how to do the math, and all of a sudden it just came to me for long enough for me to solve the algebra problem on how to do it, then it went away. Other times it was like I was possessed for a few seconds to avoid a traffic accident, or I just blurted out something to the right person without any premeditation that ended up with things happening in my favour in a big way.

Once the thing I used to be married to had to deal with an emergency plumbing problem that could have been a disaster. He was in tears, then suddenly he knew what to do. He was very psychic, by the way. He was a good predictor of events, and that saved my arse at least once.

Akashic access? Higher self taking over to avoid a catastrophe? Then there was Nicky Tesla. He was brilliant, undoubtedly because The Veil was very thin for him. Me thinks intelligence and, foresight and inventivity are all related to how in touch you are with the Otherworld. But of course it's the Otherworld entities that are ultimately in control, and not your mortal flotsam meat suit. It helps to have a good relationship with those Otherworld entities. Les Visible implies so all the time.

Unfortunately that connexion is only for what you NEED to know, and not necessarily what you WANT to know. And on occasion over-riding that connexion (It's called intuition.) can result in a big mess. Thank the gods sometimes you get two chances. Word of experience.
