did i almost die last night?

i had a super weird and intense experience last night.

i cannot exactly recall what i was doing except that i was taking a drive in my car. i was driving nice and slow in an estate road and somehow, i took a turn and entered an expressway. i picked up speed  and as i did so, decided to hit hard on the accelerator. the car picked up speed very very fast and i could feel the sudden intense pace at which things were zooming by. then something happened at the rear of my car, i grabbed the steering wheel tight as i turned and took a look. as i did so, the expressway curved to the left and next thing i knew, my car crashed into the road railings. due to the speed at which i was going, my car broke through the railings and flew. i couldn't do anything but to watch everything zip by.

before i knew it, my car crashed and everything turned dark. i felt things collapsing onto me from different directions, first from the front and then from the sides as the car got crushed. the next thing i knew, i felt an intense pressure pressing me from my back and within a split second, the pressure got so great it tore through my body. my chest was so tight it felt like it was going to explode. the feeling was intense that i woke up. panting. i felt the release of pressure in my chest as i woke up.

did i just experience a heart attack in the midst of my sleep?
