" A spectre is an entity that can think—though often primitively—and react to changes to their surroundings. They may move from room to room and usually have some kind of impetus keeping them on earth. They’re the closest to the pop culture concept of ghosts. Imprints, on the other hand, are a small amount of energy left behind at the point of death. They’re not conscious. Most commonly, they replay their death, often at the same time each day or on the anniversary of when they died. "
