We're back! On this episode, we delve into shared psychotic disorder, also known as folie a deux. This disorder is characterized by the transference of delusional ideas or beliefs from one person to another, almost like a psychological virus. It's a rarity, but seems apropos in the strange case of Swedish twins Ursula and Sabina Ericksson; after throwing themselves into traffic, one twin continues a path of delusional destruction...ending in murder.
