Panic attacks give u a feeling that u will feel a sharp pain in your chest/heart when u breath in a bit by bit. The feeling is like, "shit linpei kanna heart attack," but your mind is still very clear. Experienced individuals like RUN will then ponder in his mind whether he should alert people around him (in case it's a real heart attack) or just wait for it to pass. It can also sway sway happen to you when you are resting or even driving.
