The image below, taken using the gas discharge visualization method, an advanced technique of Kirlian photography, shows in blue the life force of the person leaving the body gradually.
According to Korotkov, navel and head are the parties who first lose their life force (which would be the soul).
The groin and the heart, are the last areas where the spirit departs, before surfing the phantasmagoria of the infinite.
In other cases according to Korotkov, "the soul" of people who suffer a violent and unexpected death, usually manifests a state of confusion in their power settings, and could return to the body, in the days following death.
This could be due to a surplus of unused energy.
