When we are just waking up and are not quite awake, that time is twilight. You are still foggy and in a dream state and the benefits from being in that state are still available to you. Thomas Edison would take naps and hold ball bearings in his hands. As soon as he would fall asleep his hands would relax and the bearings fall out and crash on the floor waking him up. This was so he could be in twilight state of being. So this is not a new gimmick.
That is also why Julie Cameron in her book on creativity has you write morning pages. We have the most amazing connections right then. You don’t want to waste it, especially if you are thinking up a new plan for something. My husband has to listen to a steam of talk from me the minute I am aware of morning. My dreams are fresh and still around. This time is almost like a vapor it leaves so quick. I have had breakthrough ideas during twilight. You can access this ability if you know about it even more and make a point to write down thoughts first thing or tell someone.
I call it waking up the giant.
