Do those know that they when they are dying?

When a person ails from a disease that have not been confirmed by any doctor, do they know by their symptoms that they are soon to die?Do those know that they when they are dying?
Depends on the symptoms. Given a year on I'm still recovering from acute kidney bomb and was hours from dying at one or two points...
One hospital said you're fine, come pay for in a few months for more test, the second said, "Oh crap..."
I honestly believe that happens within a lot of cases. It is the agency for the dieing person to do what it is they want to do until that time they die, if they are able. Obviously that probably doesn't come up if a person is kill tragically though. My mom died last year and she said to me twice surrounded by the proceeding weeks that "it isn't going to be long now" and she was right.
I also believe surrounded by the "one good day" in the past the end. Quite regularly people are so sick and dieing and for some explanation they have a terrific light of day, no pain, lots of vitality, can eat, etc. and usually a few days subsequently they are gone.
Dont know really.Unless you feel anguish etc etc.
Its always best to find check ups to make sure your 100% fine and tough.
There is silent Illness's which could lead to annihilation.
My gran's neighbour put on her coat and hat, sit in her fave armchair and announced exceptionally calmly that she be off to congregate her maker.she died 5 minutes following. Weird.
