Humans spend about one third of our lives asleep and while most of us dream regularly, some people remember their dreams more than others. But scientists still know surprisingly little about why or how we experience dreams. In this episode we find out about new research from a sleep lab in France that has unlocked a way to find out more by communicating with people as they dream. 

Featuring Başak Türker, a postdoctoral researcher at the Institute du Cerveau in Paris, and Lionel Cavicchioli, health and medicine editor at The Conversation in France.
