"Why do we dream and why do we repeat dreams?" asks Mila O'Dea, aged 9, from Panama.
Hannah Fry and Adam Rutherford delve into the science of sleep. From a pioneering experiment on rapid eye movement sleep, to a brand new 'dream signature' found in the brain, they discover how scientists are investigating our hidden dreamworld. Featuring sociologist Bill Domhoff from the University of California Santa Cruz, sleep psychologist Mark Blagrove from the University of Swansea, and neurologist Francesca Siclari from the University of Lausanne.
The Curious Face-Off
"Are machines better than humans at identifying faces?" asks the excellently named Carl Vandal.
Today’s Face Off leads our intrepid detectives to investigate why we see Jesus on toast, Hitler in houses and Kate Middleton on a jelly bean.
Face perception psychologist Rob Jenkins from the University of York explains why we're so good at spotting familiar faces, like celebrities. Plus, Franziska Knolle from the University of Cambridge discusses her face recognition study involving Barack Obama and a group of highly-trained sheep.

From stone statues to silicone works of art, we have long sought solace and sex from inanimate objects. Time and technology have perfected the artificial lover: today we have life-size silicone love dolls so finely crafted they feel like works of art. Now, with the help of robotics and artificial intelligence, these dolls are becoming even more like humans. This week we talk with researcher Kate Devlin about the history of the artificial lover, and consider what love and sex look like in the age of robots.
