A study of near-death experiences reveals surprising patterns in shapes and colors, categorizing them into four main types. Participants reported various geometric spaces, with conical shapes often associated with black-and-white visions, while curved spaces were linked to vibrant colors. The research suggests potential physical causes for these experiences, relating them to known visual disturbances. Despite the challenges in studying such phenomena, the findings indicate a predictable pattern in the experiences reported. Similarities were noted between these patterns and visual disorders, although no definitive proof of causation was established.
