Have you ever spaced out during a meeting, but been jolted back to reality by the sound of your boss calling your name a few times? If you’ve ever been in this awkward situation, you might have experienced “microsleep.”
This weird state of consciousness is characterized by brief bursts of sleep that happen while a person is awake — often while their eyes are open and they’re either sitting upright, or even performing a task. During microsleep, parts of the brain go offline for a few seconds while the rest of the brain stays awake. It’s sort of like being a zombie for a few brief moments — sans the whole “eating human flesh” part. And usually, people don’t realize it’s happening to them.
