Good to hear you do this
I was just thinking "mapping" also for you to try.
It's where you write a word or phrase in the center of the page and circle it. Then draw a line, write another word or phrase and circle it, and another line, and so on so forth until the page us filled. I find when I don't write to rhyme or reason doing this, but rather stay on the circle I'm in not recalling the previous circle, I often come up with quite a story out of it.
Because I'm artsy, I'll often get creative with my circles and lines and end up with a work of art too once the page is full. lol. I've often wondered if the result is a caption of what my mind looks like on the inside...silly huh.
