You’ve seen it a thousand times. A character lies on a hospital bed, the monitor flatlines into a piercing hum, and suddenly, they’re standing in a misty, ethereal hallway. At the end? A glowing, white orb. Someone—usually a dead relative or a generic angel—whispers for them to go towards the light. It’s the ultimate cinematic shorthand for dying. But where did this actually come from? Honestly, it wasn't always the default way we pictured the end of the line. Before the 1970s, pop culture visions of the afterlife were way more varied, often involving pearly gates or just a sudden fade to black.
Then came Dr. Raymond Moody.
In 1975, he released a book called Life After Life. He interviewed about 150 people who had "died" and come back. Surprisingly, many of them described the exact same thing: a tunnel, a feeling of peace, and that famous radiance. It shifted the entire cultural conversation. Suddenly, Hollywood had a visual template. From Poltergeist to The Simpsons, the phrase became an inescapable part of the English lexicon. It’s funny because, in Poltergeist, the advice is actually the opposite—Carol Anne is told "stay away from the light"—but the trope was so powerful it stuck anyway.
The Science Behind the Glow
Is it actually spiritual? Or is your brain just glitching out?
Neuroscientists have a much less romantic explanation for why people feel the urge to go towards the light during a crisis. When the brain experiences hypoxia—a fancy word for lack of oxygen—the cells in the retina and the visual cortex start firing sporadically. Dr. Susan Blackmore, a psychologist who has studied near-death experiences (NDEs) for decades, suggests that the "tunnel" is actually just a result of the way our brain's mapping system is structured. When the periphery of your vision shuts down due to low blood pressure, only the center remains active.
The result? A bright spot in the middle of a dark field.

Basically, your hardware is failing.
But that doesn't make the experience any less "real" for the person going through it. The surge of endorphins and DMT-like chemicals can make the transition feel incredibly euphoric. It's why people who survive these events often come back with a totally different outlook on life. They aren't scared of death anymore because they’ve "seen" the destination. Whether that destination is a literal heaven or just a chemical firework show in the temporal lobe is still up for debate, but the impact is undeniable.
Pop Culture’s Obsession with the Exit Sign
Think about Ghost. Patrick Swayze’s character, Sam, watches the villains get dragged into the shadows by creepy smoke monsters, while he gets a shimmering, beckoning glow. It creates a moral binary. Good people go towards the light; bad people get the shadows. It’s a very clean, very Western way of looking at morality.
Interestingly, not every culture sees it this way.
In some non-Western societies, NDEs don't involve tunnels or lights at all. Some people report seeing a bureaucratic office where their "files" are being reviewed. Others see a river or a specific bridge. The "light" seems to be a very specific cultural meme that has been reinforced by decades of television and film. We expect to see it, so when our brains start to misfire, that's the imagery we reach for.

It’s a feedback loop.
Directors use the light because we recognize it. We recognize it because directors use it. It’s become a shorthand for "the end is near, but it’s going to be okay."
What We Get Wrong About the Experience
Most people think the light is the final destination. In NDE literature, it's usually just the threshold. People talk about a "point of no return." Sometimes it’s a fence, a door, or just a feeling that if they take one more step, they can’t come back.
It's also not always peaceful.
While the majority of reported experiences are positive, a small percentage—estimates vary between 1% and 15%—are actually "distressing NDEs." These involve feelings of terror or being lost in a void. We don't talk about those as much because they don't make for great Hallmark movies. But researchers like Dr. Bruce Greyson at the University of Virginia have documented these cases extensively. Even in these scary versions, the light might appear, but it feels judgmental or overwhelming rather than welcoming.

Why It Still Matters in 2026
We are living in an era where we are closer than ever to understanding the biology of death. With advances in resuscitation medicine, more people are being "brought back" than ever before in human history. This means we have a massive pool of data.
The trope of the light serves a psychological purpose. It’s a comfort. In a world that feels chaotic, the idea that there is a guided, illuminated path at the end provides a sense of order. It tells us that death isn't just a "nothingness," but a transition.
Even if you’re a hardcore skeptic, you can appreciate the narrative power of it. It represents the ultimate mystery. Every time a screenwriter puts that glow on screen, they are tapping into a collective human hope that the lights don't just go out—they just change rooms.
Actionable Insights for the Curious
If you’re interested in the crossover between the "light" trope and actual science, there are a few things you can do to dig deeper without getting lost in "woo-woo" pseudoscience.
- Read the Greyson Scale: If you’re researching NDEs, look up the Greyson Scale. It’s the standard tool used by researchers to determine if a near-death experience was "real" or just a dream. It asks about things like time distortion and out-of-body sensations.
- Check out the AWARE Study: Dr. Sam Parnia has led some of the most rigorous scientific studies (AWARE and AWARE II) on what happens to human consciousness during cardiac arrest. It’s the best source for data-driven info on the "light" phenomenon.
- Differentiate between Trope and Testimony: When watching a movie, realize that the "light" is often a lighting department decision designed to make the scene look "holy." Real accounts are often much more messy, confusing, and personal.
- Look into "Terminal Lucidity": This is a related phenomenon where people with severe dementia or brain injuries suddenly become clear-headed right before they die. It’s often when they report seeing the light or deceased loved ones. Understanding this can help families prepare for the end-of-life process.
