They would sometimes wake in the night to hear a disembodied chirping somewhere in the room, or a strange, low hum, or the sound of scraping metal.
Sometimes they felt a phantom flutter of air pass by as they listened. Others in the room would often not notice a thing, the Associated Press reported, and the noises would cease if the person moved just a few feet away.
And then, usually within 24 hours of these bizarre events, bad things happened to those who heard the noises.
What exactly two dozen Americans experienced at the U.S. Embassy in Cuba — in incidents last year and then again in August — remains a mystery to science and the FBI. They have alternately been blamed on a high-tech sonic weapon or a mysterious disease, and have caused a diplomatic crisis because U.S. officials blame Cuba for the attacks.
