Some Additions in the Algorithm for Out of Body Experiences

We would like to congratulate Valarie Laws and Elanie Perry for their thoughtful paper on developing the algorithm for near body experiences (Laws and Perry, 2010). Indeed, it is of grave importance to select the cases on the basis of strict exclusion criteria, so that the sample that is obtained is a representative of Near Death Experiences (NDE) as pure as could be. However, we observe that the algorithm could have been more accurate if following points would be taken into consideration.
