I would reguard such sighting as a imprint, like a moment in time, being replayed, like a video.. So the image would have clothes, and, anything else, that represents, said moment in time. The imprint is not the soul it is the 'fingerprint left behind' of the entity. The actual soul would be an orb. Course, then they're the theory that Americans have such nudity issues that they carry that over to the other side.
