When David Eagleman was eight years old, he fell off a roof and kept on falling. Or so it seemed at the time. His family was living outside Albuquerque, in the foothills of the Sandia Mountains. There were only a few other houses around, scattered among the bunchgrass and the cholla cactus, and a new construction site was the Eagleman boys’ idea of a perfect playground. David and his older brother, Joel, had ridden their dirt bikes to a half-finished adobe house about a quarter of a mile away. When they’d explored the rooms below, David scrambled up a wooden ladder to the roof. He stood there for a few minutes taking in the view—west across desert and subdivision to the city rising in the distance—then walked over the newly laid tar paper to a ledge above the living room. “It looked stiff,” he told me recently. “So I stepped onto the edge of it.”
In the years since, Eagleman has collected hundreds of stories like his, and they almost all share the same quality: in life-threatening situations, time seems to slow down. He remembers the feeling clearly, he says. His body stumbles forward as the tar paper tears free at his feet. His hands stretch toward the ledge, but it’s out of reach. The brick floor floats upward—some shiny nails are scattered across it—as his body rotates weightlessly above the ground. It’s a moment of absolute calm and eerie mental acuity. But the thing he remembers best is the thought that struck him in midair: this must be how Alice felt when she was tumbling down the rabbit hole.
"With effortless focus, Munenori Sensei smoothly pulls the arrow to bend his bow. Released like a ripe fruit, the arrow glides. It races toward your heart.
In the eternity of the arrow’s flight, you wonder: What is this present moment? Confronting its end, your mind becomes razor sharp, cleav- ing time into uncountable, quickly passing moments.
At one such perfect instant you see the arrow as it floats, suspended between the finest ticks of the most precise clock. In this instant of no time, the arrow has no motion, and nothing pushes or pulls it toward your heart. How, then, does it move?
While your beginner’s mind embraces the mystery, the arrow flies."
Had a similar incident in my teens.
I was at scouts and we’d set up a monkey swing on a branch next to a river.
While I was on it, I somehow realised the knot on the branch was coming undone and was able to witness its unravelling in slow motion.
The fall was also slow, as I hit the ground I cried out, but more from shock than any pain.
Very luckily I had landed on the soft sandy riverbank rather than the rocks in the river I had been above just moments before.
It’s not surprising that in life threatening situations the brain would focus all of its attention on the immediate situation, rather than worrying about the usual crap the brain worries about (like paying your bills).
Something like that happened to me in first grade. I was trying to go down a slide and a friend decided to climb the slide itself. He ended up launching me off the side of the slide. It was maybe a five or six foot slide, and I remember going over the side in slow motion, grabbing for the rim of the slide but being at least 6" away from reaching it, and then suddenly.. sharp pain and pitch black as I landed on my back.
I was conscious again about 10-15 seconds later. It's the kind of thing that sticks with you your whole life. It probably wasn't close to life threatening, but the combination of adrenaline, sharp pain, and brief unconsciousness definitely leaves an imprint in your memory.
