Writing mythology

Since a few days I spend some time writing. Starting simply to write whatever comes in my mind, moved to writing  my favorite topics which I liked to read as a child and then moved to little fantasy stories and then moved to descriptions of  figures who I know from my dreams. And after a few days I realised that in fact I have started to write about my personal mythology like my plan was a few weeks ago. But at that time I didn't knew how to do it. I like the process. I am surprised how the content develops while I am writing. I can't imagine it all before I start but once I write it just grows out of the rest. I see and hear it while I write. That is a bit similar like I paint. The painting often also just develops out of some colours and movements. 
I write in Dutch my mother tongue and will have to work longer on it before I can share anything about it here.
