In studies on Near Death Experiences (NDE) data has been collected by using the recently developed scaling methods, the scale developed by Ring and the Greyson NDE Scale. In order to illustrate the problems in the empirical study of NDEs, my intention is to compare the Greyson NDE-scale with the most common theories on NDEs.  After series of modifications the final scale consisted of a questionnaire consisting of sixteen different questions, that yielded into four different areas, Cognitive components, Emotional components, Paranormal components, and Transcendental components. In the end the theory that has the most likely possibility to explain NDEs in the future must be the Dying Brain theory, but one should not disclose the different features of the Afterlife theory (but without the origin explanation).
