Sometimes, building up so much knowledge about hypnosis was a double-edged sword. She was old enough to have seen every hypnotist trick- even innovated a few ones herself. It was hard to be surprised now that she was so old and experienced.
Fortunately, she didn't always have to be so old. When regressed, she found hypnosis to be full of surprises. She delighted in the tropes- the spirals, the pocketwatches, the B movie cliches. Certainty gave way to discovery. Thoughts of technique flew away and it was all magic once again.
