The Most Disturbing Case Of 'Shared Psychosis' In Twins

Twin sisters Ursula and Sabina Eriksson caused chaos on a UK motorway by running into traffic—twice—surviving both times. Sabina was briefly detained but later killed a man who offered her shelter. She fled, injured herself, and jumped off a bridge, surviving again. Diagnosed with "folie à deux," a shared delusion likely influenced by Ursula, she served five years for manslaughter.
