You just asked for human consciousnesses on the whole, and if you say that or brain and neural system isn't a part of it, then you are a fool. Besides, even if you did manage to get the molecular blueprint of your grandmother and put it back together, you still wouldn't be able to replicate her life and the surroundings she had around her that formed what she was personally.
When I was young, there was a god with infinite power protecting me. Is there anyone else who felt that way? And was sure about it? but the first time I fell in love, I was thrown down - or maybe I broke free - and I bade farewell to God and became human. Now I don't have God's protection, and I walk on the ground without wings, but I don't regret this hardship. I want to live as a person. -Arina Tanemura
