What if hauntings are not emanations of spirits of the dead? After many years of investigating the paranormal, Nick Groff has new thoughts as to the nature of ghosts and offers possible explanations for some of the most common paranormal experiences. For example, some ghosts may be thoughtforms created by the living, or shadow figures may be higher forms of life exploring locations with high emotional energy. He posits that many hauntings may be the result of some sort of slippage in time, where we can see and interact with people in the past or future.
