No, and that is the best kept secret by medicine (and I wonder why?).
Society leads us to avoid talking about this process and even to replace the word death with euphemisms, and makes it much more difficult for us to deal with the loss of a loved one. Instead of saying that someone is dying, it is said that he is "seriously ill".
When the family is near the bed of someone very sick, who is about to die, they do not know what to say to each other or to the person who is dying, and the person who is dying does not know what to say, nor what to expect, and can If you are wondering if this is your last breath, the scene is marked by sadness, anxiety and despair.
Death is as natural as birth, but religious dogmas have made us lose the immense human wisdom to accept death in a normal way.
Dying, as well as being born, is simply a process, in which gradually, the person gets tired, exhausted, and as time goes by he slowly goes on sleeping more, remaining less awake. The person seems to sleep, but the truth is that he is temporarily unconscious, you can not wake him up, not even to administer medication, you can not tell them that a visit has arrived. When they wake up, they say they have slept very well. That is why it is known that this coma is not terrifying. The patient does not notice this moment of loss of consciousness at the moment it occurs. And as time goes on, they are less awake, more sleepy, until, in the end, they are unconscious all the time.
The patient will feel so relaxed that it will not clear his throat and he will continue to breathe with a bit of mucus or saliva in the back of his throat, and that may generate a strange noise, that some associate that sound of death as something strange. But that means that the patient is so relaxed, in a state of unconsciousness so deep, that not even the saliva in the throat tickles them, when air bubbles enter and leave the lungs.
In the last moments of life, there is a period of shallow breathing and then an exhalation that is no longer followed by an inhalation, and is sometimes so mild that family members do not realize it.
Therefore, normal death is really a quiet process, something we can recognize, for what we can prepare ourselves and something that we can perfectly deal with.
