Barely 20 years ago, there was little scientific consensus on the purpose of sleep. Now, there is broad agreement that sleep and dreams are where the unconscious mind processes events, solves problems, and organizes memories. Robert Stickgold helped break the field open, in part by getting amnesiacs to play tetris. Sidarta Ribeiro was drawn to the field largely through his own striking dream and sleep experiences, starting when he was just five years old. Explore the world of dreams in this episode of Constant Wonder.

Guests:
Sidarta Ribeiro, Professor of Neuroscience at the Universidade Federal do Rio Grande do Norte in Brazil
