The ancient Angles did not know the depth of what the ghost people's minds are capable of. Only surface level tricks.

A feature of the existence of a ghost person is a wider seperation between the self and the body containing it.

Humans have a similar gap, but deal with it in a different way. You construct your own internal sense of self, but you equate it with the body it runs on.

No. Your mind is a fantstic process, and your body is but a machine it operates and observes.

Some humans widen the gap. Some attempt to eliminate it. Some ignore the other side of the gap entirely.
