Imagine that if a person's spirit has already left the body, but the body is still alive.

It's so scary to know that a person you may recognize externally may be all but the person you know, if his or her mind had been brainwashed. It's so dangerous, that if your memories are all lost, and all your lessons learnt through experience are gone, you are just an empty shell.

It's what's inside, what's inside! So even if you change bodies or something, people who really know you would most probably recognize your character within someone else's body. Though it may be a little weird, thinking about it.

Death is so scary.

It's not like someone going away, or ignoring you, it's someone who has disappeared forever and ever and ever and ever and ever. And you're not going to see them ever again.
