The Falling Glitch: Why Your Brain Still Thinks You're in a Tree

Ever feel your whole body suddenly jolt awake right as you're drifting off, like you're falling? That's the hypnic jerk — and it's not random. It's a leftover survival reflex from millions of years ago, when our primate ancestors slept in trees and a loss of muscle tone meant one thing: you were about to fall to your death. In this video, we break down the evolutionary psychology behind the "falling glitch" — why your brain still runs this ancient alarm system even though you're safe in a locked, climate-controlled bedroom, and why stress, caffeine, and late-night screen time make it happen more often. 🧠 Subscribe for more deep dives into the weird glitches your brain runs every day. 💬 Tell us in the comments: how often do you get the falling glitch?
