What is that supposed to mean?
It’s not complicated. When you see someone moving around on their own, they aren’t dead. A body that has no brain function at all is dead. If a person is moving on their own, that means they are alive. If they are alive, there is some brain function. The mythical world in which zombies move around at will, even though they’re dead, is pure fiction. It’s quite possible for a person’s brain function to be below the threshold deemed by the death mongers to qualify them for the rights of personhood, but someone like you should be careful about that.
