I think I saw death (no joke). I want a scientific explanation
Years ago my little sister was choking on her food. She was coughing heavily and my mother had to pat her on the back. Because I knew it was serious I walked into the room. As I came in the room filled with darkness. It was like a dark fog falling from the ceiling with the speed of a feather that floats to the ground. The occurence lasted about 2 seconds. I guess it was over when my sister was fine again. No one but me saw it.
Sometimes I think of this and now I googled if anyone made a similar experience. I found the report of a nurse saying she saw a dark, thick rolling fog when she entered the room of a patient and she too thought it was death. She said the patient died later that day. I can link the source if wanted.
My sister is still alive. Maybe death was there because it expected to get her. If it was death. I never saw this before and never again after.
I don't know if it was death but I know that what I saw was real.
I want a scientific explanation. I was not in a panicking or scared state, just worried. My mind was clear, not under the influence of an adrenaline rush, medicine, drugs, alcohol, sickness or anything else.
Momentary loss of blood pressure due to mild shock in a very tense situation caused your vision to go blurry a little bit.
You were probably too focused on your family at the time to notice any other symptoms. You may have also felt faint, dizzy, or been unable to move your body during those couple seconds as well.
