All of us probably hallucinate to some degree or other. Some people hardly ever have these kind of anomalous experiences. Other people at the other extreme might be somebody who's going through a psychotic breakdown. But there's also all points in between. And there's an area where people might have quite a lot of these experiences. They might hear voices, they might see things that other people don't see and so on but not actually be worried about it. And maybe even think it's a gift.
