What Happens When You Die? Woman 'Dead for Eight Minutes' Says She Met Mysterious Beings

Brianna Lafferty says that during eight minutes without a heartbeat, she experienced a world unlike the one she knew.

After suffering cardiac arrest, the 33-year-old woman described leaving her body, entering a place where time seemed to disappear and encountering mysterious beings she believed were not human. When she survived, she was left with an experience that changed the way she viewed death.

Stories like Lafferty's are often described as near-death experiences, but they raise a question science has yet to fully answer: what is happening inside the brain when a person is close to death?

Her account may sound extraordinary, but near-death experiences have been reported by people who survive cardiac arrest and other life-threatening events. Researchers have been studying why people can report vivid images, altered perceptions of time, encounters with other beings and sensations of leaving their bodies.

Lafferty's experience may be deeply meaningful to her, but it is not scientific proof that consciousness continues after death. Instead, it offers another glimpse into one of medicine's most mysterious frontiers: what happens to the brain as the body begins to shut down.

What Did Brianna Lafferty Say She Experienced?

According to reports of her experience, Lafferty described feeling as though she had left her physical body and entered a different state of existence. She said she encountered beings she believed were not human and experienced a sense that time and physical reality no longer worked in the usual way.

Experiences like these are generally described as near-death experiences (NDEs). They can involve sensations such as leaving the body, seeing a bright light, encountering people or beings, experiencing profound peace or feeling that time has changed.

The experiences can feel completely real to the person who has them. However, their interpretation is separate from what can be established medically.

What Happens to the Brain During Cardiac Arrest?

Cardiac arrest occurs when the heart stops pumping blood effectively. Without normal circulation, the brain no longer receives the oxygen and nutrients it needs, and the person typically loses consciousness within seconds.

Importantly, cardiac arrest is not necessarily the same as irreversible death. CPR, defibrillation and other emergency treatments can sometimes restore circulation. However, the longer the brain goes without adequate blood flow, the greater the risk of permanent injury.

Research has detected periods of organised brain activity around cardiac arrest and during resuscitation. A 2023 multicentre study found that some cardiac-arrest survivors reported memories or perceptions suggestive of consciousness during CPR, while EEG recordings showed periods of brain activity consistent with consciousness. However, the findings cannot establish what any individual patient was consciously experiencing.

Why Do People See Lights or Feel Like They Leave Their Bodies?

There is no single explanation for every NDE. Scientists have proposed several possible mechanisms, including changes in oxygen levels, blood flow, neurotransmitter activity and the way the brain processes sensory information during extreme physiological stress.

The feeling of leaving the body may involve disruption to brain systems responsible for integrating information about where the body is located in space. Other elements, including bright lights, vivid memories and encounters with beings, may involve changes in perception and memory during severe physiological stress.

These explanations remain areas of research and may not account for every detail of an individual experience.

Can Science Explain Near-Death Experiences?

Scientists can investigate the physiological circumstances surrounding an NDE, but they cannot directly measure the subjective experience after it has occurred.

A person may genuinely remember seeing a light, meeting someone or feeling detached from their body. That does not establish that the experience occurred outside the brain, nor does it prove that it was simply a hallucination.

Researchers continue to study NDEs through neuroscience, psychology and resuscitation medicine. There is currently no scientific consensus that near-death experiences demonstrate an afterlife.

Why Can Time Feel Different During an NDE?

Some people report that minutes felt much longer during an NDE, or that the experience unfolded outside ordinary time.

The brain's perception of time can change during extreme stress and altered states of consciousness. Memory can also influence how an intense event is reconstructed afterwards, potentially making it feel longer or more detailed than its actual duration.

Lafferty's description of experiencing an extended period during a much shorter cardiac-arrest event therefore cannot, by itself, establish that she was conscious for every moment.

Brianna Lafferty's account of being 'dead for eight minutes' and encountering mysterious beings is a striking description of a near-death experience. But while her experience may be deeply meaningful to her, it cannot establish what happens to consciousness after death.

Medicine can explain what happens when circulation stops and how the brain can be affected during cardiac arrest and resuscitation. What remains less certain is exactly how the brain produces the vivid experiences reported by some survivors.

For now, NDEs remain an intriguing meeting point between neuroscience and one of humanity's oldest questions: what happens to consciousness when the body is dying?
