This is quite possibly the most spine chilling video you’ve watched and would not advised watching if you had weak heart.

The footage, believe to have been been shot in former morgue in Brazil showing a door banging and the noise can clearly be heard.

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.

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.
