Near-Death Experiences (NDEs) are commonly portrayed as passing to an afterlife, but empirical research is recent and their definition remains debated. Questionnaires used to identify NDEs may be restrictive and subjective. To address this, researchers analyzed freely expressed narratives from 158 participants who reported a firsthand NDE, using automated text-mining. The analysis identified the most common words and, through hierarchical clustering, revealed three main clusters of features: visual perceptions, emotions, and spatial components. The authors suggest that this user-independent, data-driven approach can help build a more rigorous description and definition of NDEs.
