Innocent till proven guilty. Can you imagine how damaging and frustrating and what mental torment you would be in if you could see things that others could not? The damage you could do to a person telling them what is really happening is not real, the mental torment you would put this person in, you would be the one causing the damage.
IMHO very sadly many people have seen the spiritual, have totally normal functioning minds but were made mentally ill by people trying to convince that they are mentally ill.
