CAMBRIDGE, Massachusetts—Study released Wednesday sheds new light on what happens after humans die journal of neurology It turns out that the nightmare never ends with death. “The consensus among scientists for decades has been that when life ends, so do nightmares,” said John Simmons, a neurologist at Harvard University and co-author of the study. It proves we were wrong: urges can still be detected in the human brain, but only in the amygdala and hippocampus, the parts responsible for the most painful, terrifying and humiliating dreams. research shows that long after death, our bodies decay and there are fewer and fewer of us physically, but there is actually a very powerful psychic perception behind us, but the most Limited to hallucinogenic visions of terror as we relive the unbearable panic, afflicting our psyches that have endured in life.From a clinical standpoint, there seems to be no way out. Simmons added that the situation was somewhat different if the body was cremated, observing that in these cases the brain merely recorded a continuous burning sensation that lasted forever.
