““While much of the evidence is anecdotal, there are numerous cases where an apparition was witnessed by more than one person or where an individual was later able to verify details they had observed during their astral journey. There is also solid scientific evidence for the existence of the etheric double gathered from experiments conducted in the mid-1970s by Dr Karl Osis of California, USA during which the invisible presence projected by a psychic in an adjoining room was recorded either by photosensitive instruments or sensors which could detect the tiniest movements of a feather in a sealed container.””
