I've been keeping a sketchbook for about 10 years now and they're an interesting record of my mental state. When I first started getting on heavy psych medication my brain had a whole reality adjust period for about 2 weeks, there's this really interesting section of a weird kind of word-salad combined with terrible drawings of mutilated hands and flowers dripping ooze. So, who knows.
Things are much better these days, though my current book is at least 20% the word 'no' or 'nope' repeated over and over again, and another 30% sketches of disgruntled cats.
Oh hey, one of my old sketchbooks.
Wow, I was really messed up back then.
Not like these days
