When you actually talk about precog with psychics, people who are really good at precog, you get into weird words.
Because the future is not set. Or, the futures are not set. Or the future you seem to be heading for is X, be sure to watch out for a thing like Y. (not Y, a thing, like Y.)
It is all there in the field. Because you are drawing in a future, and that creates the now. So, if you are sensitive enough, you can see it unfolding.
But, looking at it does change it.
