near death

Some people who survive cardiac arrest — heart stopped, no pulse, no blood flow to the brain — report vivid experiences: a tunnel, a bright light, a sense of leaving the body. The term "near-death experience" only dates to 1975; a landmark 2001 prospective study of 344 cardiac arrest survivors found 18% reported one, and couldn't identify any physiological or psychological factor that predicted who would. A 2023 study went further, putting brain-monitoring equipment directly on cardiac arrest patients during CPR, and found something doctors had assumed was impossible: in some patients, brain activity matching conscious thought came back during CPR itself, in a window long thought to be electrically silent. That doesn't prove the brain was inactive during the experience — if anything, it points the other way, toward the experience happening as activity returns rather than during true silence. Proposed causes include low oxygen, a flood of the brain's own chemicals, and dream activity leaking into waking consciousness — though researchers in the field are openly divided over whether those fully explain what survivors report. Whatever the full explanation, the experience shows up in strikingly similar form across very different cultures, even among people with no prior belief in it.
