Imagine being on a roller coaster without a lap bar or shoulder harness, spinning upside down, swirled around in circles like a Gravatron at a fair and the floor drops. You want to pass out. You have no control. You feel frozen in time yet want to die or the ride to stop at any cost. You can not control the ride, your emotions, thoughts, feelings and feel 110% helpless. All that happening while replaying what terrified you in the first place and then it plays over in your head over and over and over. Reliving the event every time.
