It's odd that they come out of anything, and don't just materialize in the room.Jay, I like the Tin Foil Hat podcast. I haven't listened in a while. You have refreshed my memory to go listen again. I can't say that I've had that experience though. Seeing anything appear out of a wall especially a hand would be terrifying. If these reports are real and this does happen, what is the nature of these entities? Are they spirits of the dead in energetic form that can exist inside solid matter? Are they interdimensional beings? Aliens? It is really one of the great mysteries of life.
