My mind has been bugged for a bit with questions. On the ToZ site it says that some ghosts don't even realize they're dead for years. How do you not know that your dead? Are you just constantly less conscious as a ghost? And i didn't totally understand some of the other details.
Are spirits in a sense; sleeping when they do things they did when they were alive like when people say they see the maid who died cleaning, sort of like when people sleep walk. Or are any repetitive actions of the ghost just residual energy? And if so how can that much energy be produced?
