We are going to have nightmares after this and we weren't even there. The screaming…
Brazilian TV show Programma Silvio Santos organised this 'Ghost on the Subway' prank for a segment. With hidden cameras installed, they rigged a subway car so that the lights would flicker when it arrived at a station.
As the unsuspecting passengers try to get the locked doors to open, everything goes black and when the lights come back on, there is a ghostly girl standing in the carriage, holding a doll. And then she screams.
The reactions of the passengers are fascinating to watch. Some scream back, others cover their eyes, some remain calm - and two of the guys hide beneath the seats.
We're surprised no one attacked her.
