On August 15, 1984, a truck carrying 12 passengers was traveling along a road by Lake Minao in Cameroon. As night fell, a dense fog emerged from the lake and quickly covered the area. Despite the fog being a common occurrence near the water, the driver encountered an issue when the truck's engine sputtered and shut down, leaving them stranded in the fog. The vehicle came to a halt and the driver was unable to restart the engine. The passengers were left stuck in the eerie and thick mist, unable to continue their journey.
