Luminous flash and headaches in Carentoir

Summary

One night in July 1979, two people in Morbihan experienced sudden severe headaches at the same moment a luminous flash lit up their bedroom. The symptoms vanished along with the light. Looking out the window, they saw several luminous beams projected onto the road. A local newspaper later mentioned patches of burned grass in a nearby field, though neither the outlet nor the date was specified. The testimony only reached GEIPAN in 2009, and no other reports were found.

Classified "C", the case presents an intriguing coincidence between the luminous phenomenon, the physical symptoms and the alleged burned-grass report, but the lack of verifiable data prevents any rigorous investigation.
