Near Death Experience - NDE
With so many people getting revived with today’s modern medicine the increase of NDE’s are also increasing. Many times these people will feel like a different person after their experience of being out of body. As I have had two such experiences myself I know how difficult it can be to make sense of what happened.
A good resource to start to understand what you may be experiencing is to visit the website for the International Association of Near Death Studies, IANDS.
