Believers accept reports of ghostly encounters as facts, from friendly, harmless manifestations to malevolent episodes in which they terrorize and harm the living. Different types of ghosts include human spirits, animal spirits and demons. Ghosts remain aware of their personalities, memories and emotions from their lives.
Spiritualists believe that ghosts communicate by inducing thoughts and via automatic writing. Ghosts may appear to the living in orbs, light, shadows, mists and blurs, but appearing in full form is rare. Haunting occurs when a ghost wants attention, and sometimes the ghost is unaware of being dead.
When the temperature of a room drops suddenly, it means a ghost is present. Poltergeists are ghosts who play tricks, such as moving objects or turning lights on and off.
