This video went viral for showing the disturbing reaction of a medium named Socorro Leite, who visited the former Carandiru prison, in São Paulo, Brazil, before it was demolished.

The prison was marked by the brutal massacre that took place on October 2, 1992, when an intervention by the Military Police to control a riot ended with 111 inmates dead. While walking through the abandoned place, the woman said she felt a “heavy” energy and strange presences inside the cells, something that left those filming the scene shocked.

Carandiru was demolished in 2002 and to this day remains one of the darkest episodes in Brazil’s history.
