Most people struggle to stay off their phone for five minutes. One scientist decided to go a bit further—by locking herself inside a pitch-black cave for five days. Armed with biosensors and scientific curiosity, bioengineer Kiana Aran turned total darkness into an unusual experiment on the human mind and body. With no light, no sound, and no sense of time, her brain started behaving in surprising ways, from heightened senses to vivid hallucinations. The results didn’t just test her sanity—they opened new clues about how humans process the world when the outside world suddenly disappears.
