A Near-Death Experience (NDE) can be defined as the reported memory of a range of impressions during a special state of consciousness, including a number of unique elements such as an out-of-body experience (OBE), pleasant feelings, seeing a tunnel, a light, deceased relatives, or a life review, and a conscious return into the body (van Lommel, P. , 2017)
