Why Humans Fear the Dark Fear of the dark isn’t childish. It’s ancient. For most of human history, darkness meant danger. Predators hunted at night. Vision failed. Sound became unreliable. Our brains learned one rule: Darkness equals risk. Even today, the same survival wiring remains. Your fear isn’t imagination. It’s memory. Not personal memory — human memory.
