Ever work in your office late at night? No one else is there, it's quiet and suddenly there is an unexplained noise. You mind races to think of all of the horrible things that could be lurking in the dark. That's our brain's way of helping us survive, believe it or not.

Greg Williams and Brian Marren from Arcadia Cognerati share with us how the human brain works to keep us safe even though we are spooked. They also tackle the question if it's even possible to see a ghost in the first place.
