Technically this would count as an Annoy. It's what happens when I'm trying to draw something to get better acquainted with on a regular basis (in this case, drawing people). Well, they don't speak to me at all, so it all goes downhill from there. The creatures arise out of my sub-consciousness as if in protest.
I guess that's the trick. Draw something long enough to the point that it frustrates you, until something else unexpectedly comes out of it.
Frustration is the fuel, surprise is the payoff. That can be a burden at times.
