Don't be disturbed, Freeper Friend. Whatever those things are, they are not the souls of deceased persons, because Scripture assures us over and over that the dead go immediately to either Heaven or hell.
I believe many of these things are simply demons, "getting their kicks" by fooling people. It is also possible that the enemy of our souls somehow filmed some people while they were alive on earth, and those films are being played back so the demons can laugh at the reaction they get.
Be at Peace in our Loving God, my friend. Remember, the Enemy of our souls is a Liar, and one of the main Tricks of his Trade is Deception.
Well said. On the other end of the scale is the belief that "good" people die and become angels (e.g., "It's a Wonderful Life").
