A state of being that artists go into when drawing (or trying to draw). Often involves dehydration, a headache, and a sudden hatred of everything, plus other things like back/wrist pain and overstimulation. In this state, the artist is usually very focused on their work and would probably prefer to remain in this zoned-out phase for as long as possible.
Not confined to digital artists.
