Do you think that inanimate objects (as in bricks) hold the energy of past events?
This is an interesting question. Let’s get the easy question out of the way. Can you relive the past from touching a castle wall? No. Maybe if you knew the history of a certain place one may be able to add to that history by touching a wall or dipping your hand in a nearby stream or feeling the ground or floor beneath you. All of these are physical attributes of a certain area which can add a feel for the history. Either you will add more understanding of the setting you’re in or maybe you would find that many the suroundings were changed by a war, battle, natural occurence, agriculture, or however the land was used. However, to touch a wall and explicitly re-live a battle is science-fiction. The other two questions seem to me to be related more. Scientifically speaking energy is a form of matter and matter is a form of energy. In other words, they change back and forth, matter to energy and vice-versa. Recalling from basic chemistry and physics, matter is everything including energy.
