The part of the mind creates some ideas, images, concepts, vision, insights, invention, innovation, interest, fascination and etc.
I know that you know the meaning but for the clarification of things I just like to brought it up.
Sometimes or rather Always, I imagine things that I should be doing. I also apply it in my everyday life whenever I am free and totally into something.
Although there are times its just an imagination and nothing has been applied to what I want.
I will not imagine things that are too difficult to do, despite that Its really fun to imagine things that are impossible lol.
