Brian Cox and Robin Ince are joined on stage by Professor Russell Foster, Professor Richard Wiseman and comedian Katy Brand as they attempt to get to grips with the science behind Robin's insomnia. They'll be asking why we sleep, is 8 hours really enough, and why has every creature on the planet evolved with some period of inactivity? They'll also be investigating the purpose of dreams and whether analysing them has any useful purpose? Was Freud right with his symbolic interpretation of dreams, or if we dream about aggressive courgettes, does this reveal our inner most anxieties about.... aggressive courgettes?
