Ghost Possession or Influence

This video shows what some may believe to be demons possessing people.

On Angels & Ghosts, we do not teach demons to be Hollywood-esque entities; it is a phenomenon that is often mislabeled and feared (of course). Negative ghosts that behave badly do exist, often portraying themselves as mightier and scarier than they are - ill-behaved, trick-playing ghosts (a small percentage may even exhibit downright evil behavior). This begs the question: Can ghosts influence people (attach their attention to another), causing the strange mental behavior in people?

Watch the video and decide if ghost possession, or influence, is real.
