This video apparently shows a poltergeist at work – and is quite possibly the most spine chilling video you’ve watched in ages.
The clip is filmed from the point of view of what appears to be a security guard who is clutching both a torch and his camera phone.
He is shown following another man as they both walk down what looks like a badly lit corridor.
Meanwhile a sinister banging noise can be heard.
As they continue on slowly, the viewer cannot be sure what is happening – mainly because the light ahead is defective and flickering.
But as the men walk further forward it becomes apparent that a red door is slamming open and shut.
Yet, terrifyingly, there seems to be no-one about.
This video was shot at a “Center for Comprehensive Care for Children and Adolescents” in Brazil.
