The problem I have with pictures in my head is that they play over and over and won't go away. I'll have a scene or several that literally keep me awake in the small hours of the morning, and the only way to stop them is to write them down.
That too! This discussion has been fascinating and is very reasuring somehow. I thought I was the only one that kind of thing happened to, and distinctly remember being told off when I was little for being caught under the bedclothes with a torch writing down an idea that would leave me alone. I haven't changed much ;-)
