At the Hour of Death

At the Hour of Death is one of the landmark publications of empirical survival research — parapsychologist Karlis Osis's systematic study of the dying experiences reported by thousands of physicians and nurses across the United States and India. Rather than gathering anecdotal accounts, Osis designed a structured survey methodology that allowed him to collect and analyse data from medical professionals who had observed hundreds of patients in their final hours, asking specifically about the visions, altered states of consciousness, and anomalous experiences that occurred in the period immediately preceding death.

The findings are striking in their consistency across cultures, religious backgrounds, and levels of consciousness medication: visions of deceased relatives and friends coming to accompany the dying, elevated emotional states (peace, joy, radiance) that occur independently of medical condition or drug administration, and anomalous knowledge or experiences that cannot be explained by the physical state of the brain. The cross-cultural comparison between American and Indian data is particularly significant: despite major differences in religious belief and cultural expectation, the core features of the dying experience showed consistent cross-cultural patterns — suggesting that what was being reported reflected genuine experience rather than culturally conditioned expectation.
