Why, when we’re alone, do we sometimes feel like we’re not? Why are we eager to find signs of life in our surroundings — to see faces in clouds, or to get creeped out when the house creaks at night? 

Dessa investigates some of the most mystical, disorienting and disturbing experiences a person can have. She discovers that neuroscience, the study of our brains, might just help explain this big, important chunk of being human.

Deeply Human is a BBC World Service and American Public Media coproduction with iHeartMedia.
