Ha,ha,ha, This is ADAMS famous claim Jane,not mine.
Of course, it maybe on another thread, but I can't find those exact words you claim Adam said, on this one, although he does highlight, several times, about her drowsy state due to medication. It's perfectly possible that, had she been in a very deep sleep because of her medication, she wouldn't have heard anything had there actually been anything to hear, but this is something we can't know.
