As someone who has had that flight / flight response many times as a result of anxiety I think that poster was being literal, not figurative. Also, thank you for posting this; though I've come to learn to manage my condition with sleep, exercise and mindfulness meditation it's nice to see the other thoughts on the subject and see that many others are helped by the same things I've come to over many many years working on this on my own.
