If my heart stopped beating, would I have enough energy to walk out into the other room 20 ft away before I passed out and died?

One day in September I suddenly started having symptoms similar to cold or flu. That day was very hot so I thought my symptoms were partially caused by high temperature outside. I drank some water and waited until late afternoon till it became a little colder. Then I went outside to do some shopping and my other everyday businesses.

Only when I sat on my bed, my blood pressure and counsciousness slowly went back to normal.

Really bad things started to occur at night when I was preparing myself to go to bed. Last thing I was able to do with no issues was washing my teeth and right after that I started feeling that my blood pressure decreased rapidly. After a couple of minutes it came to a point that I couldn’t think anymore and I wasn’t even able to recognize myself in the mirror. I was just standing, holding on to the sing, looking at the mirror, and I was like Who the f-word is that?

If Jesus was crucified by Governor Pontius Pilate, why does the Quran deny his death?

It was like my consciousness was about to switch off completely in a matter of seconds. The only things I had in control were my limbs so I kept holding on to the sink and did my best not to fall to the floor. Since I also had some control over my legs, I tried to make some steps and VERY slowly I managed to get from the bathroom to my bedroom. Now I realize it was pretty dangerous since it involved walking up the stairs to the upper floor, however, I always had something to hold up to.

Not sure if this is going to be a good answer to your question but I can share some bad experience I had in September this year, since it may in some part describe the way you could feel when something like this happened to you.
