#29 Strange Noises
In 2016, a young CIA officer reported suffering from headaches, dizziness, and nausea. Sometime later, more CIA officers checked into medical centers with similar symptoms.
In each of these cases, the victims reported having heard strange noises resembling marbles falling on the floor.
These reports left medical experts baffled since the victims’ analysis showed no signs of concussions.
Since this incident started in Havana, the Cuban government was repeatedly questioned but gave no admission of guilt.
To date, no answer to these mysterious noises has been found.
