@Germlat,
That's only one type of 'mind over matter.' The majority of humans believe in one god or another - even when there's no evidence of one (or more). They believe their god created the heavens and the earth, but that's based on 'faith' only; it's not scientific.
Yes, out of body experience is the mind playing tricks on the individual who believes they saw their own body laying on their death bed.
Humans ability to 'see' things that doesn't exist is normal, but not factual.
