no, HI is more "material" . If you are familiar with closed eye visuals (CEV) , you might know what I'm talking about.

Pretty much like you are laying down, drowsy and suddenly something appears to you. It might be a pretty banal image like a wall or a room. It might be something as exotic as a firework For a few moments you are able to perceive the image and even shift your eyes and look at different parts of the image. However, too much attention makes the image disappear. Important thing is that the image is almost always *completely independent* of your thoughts.
