We have all asked ourselves what is really happening to the person at the moment of death.
This is not weird because everyone thought about that. Lots of rumors and beliefs have been discussed regarding this topic, however, experts came to the real answer. According to the American Society of Chemists the feeling before death is compared to the feeling when you watch a very scary horror movie as they discovered that the brain reacts in the same way in both cases.
Fear actually prepares us to react when we are in danger. There is a part in the brain named thalamus and it is very sensitive to stress and with a chemical reaction in the brain we come into state of “flight” or “fight” thankfully to the hypothalamus.
How we get this strength?
The hypothalamus stimulates the adrenal gland in order to secrete adrenalin. In this way the body is prepared for action. The adrenalin travels to the liver when the secretion of sugar in the blood is stimulated. The strength is gained in this way. If this does not help, then people start screaming (just like in the horror movies). The interesting part here is that the screams are not perceived with the same brain part as the speech. When we hear someone is screaming, the sound goes from our ears directly to the part of the brain named amygdale.
Now picture yourself in one of those horror movies and somebody is chasing you with an axe to kill you. You start screaming, but that won’t help. What you will feel next if the killer catches you and stabs you with the axe is that you will feel pain which will not be the same one as you are used to, but a kind of pain which will send a message to the brain that something really bad is going on and that it should never be repeated. The killer will stab you in the neck, your heart stops working and you eventually stop breathing (this is a clinical death). At the same moment the brain continues working like never before and that is why some people said that they have seen light or other strange things (people who survived clinical death).
If emergency help does not arrive the brain will stop working as well and biological death comes along
