A certain psychic says about her abilities when she was still at school: Another useful discovery from my school days was that I knew whenever our teachers were planning any sort of surprise test. It was never like a light bulb going on. It simply occured to me on the walk to school. I would just be walking along, thinking of nothing in particular, and it would float into my head - test today!
--- I'm not sure I understand that "light bulb going on". What was she trying to say?
