"Imaging Streaming" technique for painting subjects

Julie Heffernan is a great artist to observe.  She has a unique painting style and uses an "image streaming" method to capture compelling painting subjects.  I've been interested for some time in painting some of the images that come to my mind before and after sleep.  They seem so much more interesting than anything else I strive to come up with.  This is one painting in which I did manage to capture a vision as I was awakening.  Based on Da Vinci's "Five grotesque heads" drawing, the picture came to me one morning with the cast of characters from the last Republican administration.  I'm hoping to be able to capture some more of the visions that float through my head and put them down into paint.
