Even in the stillness of sleep, the human brain does not surrender its ancient duty of vigilance. Researchers at the University of Salzburg have confirmed what evolution long ago encoded into our biology: the sleeping mind continues to scan the sensory world, treating unfamiliar voices as potential threats and familiar ones as safe passage. This quiet watchfulness — efficient, automatic, and invisible to the dreamer — speaks to a deeper truth about what it means to be a creature that must survive the night.
