One of the most fascinating things is to see what your hand will draw when you simply start without weighing your mind down with any sort of plan of how it will turn out.
Moving the pencil along the paper. Inventing a the rules as you go. Drawing can thrive with uninhibited mark making.
And sometimes I wake from dreams, wondering how on earth my mind concocted those images. Such idiosyncratic feelings and subtle, particular events.
One reason that I make pictures is because I have a wild imagination. If it is not focused and reigned in, the scenarios my mind will cause me all sorts of stress and anxiety. To purposely create poetic stories is empowering.
