Can an actual delusional disorder be transferred from one person to another? Is "madness" contagious? During this episode, we discuss the curious case of the Eriksson twins, who to all who knew them seemed to be completely normal and never displayed any outward signs of mental health abnormalities. Then, when the sisters met up one day in 2008 after living oceans apart, they went on a road trip from Ireland to England under strange circumstances, and based on their actions, seemed to be neck deep in their own shared paranoid delusions, which caused them to run head-first into oncoming traffic and for one of them to stab an innocent Samaritan to death.
