Colour-changing luminous ball seen by a half-asleep man in Nancy

Summary

On 21 April 1988, a man in Nancy was woken by a very bright white light. He described a luminous ball that moved slowly, changed colour and shrank in size. The witness himself acknowledged the dreamlike quality of the experience, as he was still half asleep. The gendarmes investigated and judged the testimony insufficiently credible. GEIPAN classified the case as B, considering the probability of a genuinely anomalous phenomenon to be low.
