@Mame,
Some will say that intuition, your gut feeling is meaningless, even foolish to pay attention to.
I disagree. My "gut" has never led me the wrong way.
Your gut/intuition is the part of you that is always alert, that takes in the nuances your conscious mind doesn't.
I guess if you were to ask some people why their gut was telling them something, they would say "I don't know"
There have been many times I've examined why my gut's telling me something, and there has always been a valid reason. It's not magic, or a mystery. It's being attuned.
As far as psychic ability...
I believe everything exists in a multidimensional web. Not just in space, but in time.
Some people are able to see some of the other threads, going off to the past, future, and other places.
Some beings who live on another thread might take it for granted that they can see much more of the web than we can.
