" The energy from that event is stored and released at any given moment, resulting in a playback just like a tape recording. The spirit usually acts out the event with no regard to the living in its presence. It’s similar to imprint theory in that it explains residual hauntings, but differs in the material that stores the energy. Imprint theory states our energies are stored on the fabric of the universe, which is composed of time and space by a process that we have yet to figure out. Stone tape theory states that certain types of rock store the energy of significant emotional and traumatic events inside them. "
