Other phenomena include visual images, tactile sensations, such as a feather brushing down your arm, voices and apparent psycho kinetic movement of objects, and sometimes a faraway voice or scream. Visual images are seen only in a small percentage of reported cases. However, a camera will often pick up the outline of an Apparition. A study of Apparitions published in 1956 by American psychic researcher Hornell Hart and collaborators showed no significant differences between characteristics of apparitions of the living and the dead. They appear to be the same.
Some apparitions seem corporeal, while others are luminous, transparent or ill defined.
They cast shadows and can always be reflected in mirrors. Some may have jerky and limited movements, while others are lifelike in movement and speech. Apparitions invariably are clothed. Ghosts will appear in their period costumes - hence the tradition of Halloween Costumes. Apparitions of the living appear in the moment.
