 In the listed investigations as well as others, spiritualistic researchers concluded to have received detailed reports from the spiritual dimensions describing a vast, inhabited world in the astral planes.The spirit realms are described as dimensions or planes distinguishable by the differing densities and vibratory rates (or frequencies) of the substance they contain, and the various dimensions are said to interpenetrate, just as do the spiritual bodies inside us.Such research – and hence its outcome – is controversial, and the principles underlying it as well as its methods are regarded as pseudoscience in the scientific community.
