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.
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.
