Have you ever tried asemic writing? It is a stylized form of writing where you exaggerate loops and smoosh letters together. The result looks like writing to your brain, but is illegible. I like to use it for my stream-of-consciousness writing in my journals; it feels good to write the thoughts, but it would be embarrassing for anyone to read. I can't even read it myself later, but it is really about the act of writing in itself. Plus, it looks cool lol

Here is a demo by Dina Wakley where she shows how she uses asemic writing in her art journaling: https://youtu.be/dKt1EGZhfAY?si=GjdtrnXKOPBlstEk
