One minute Jonathan Reed was hiking with his golden retriever in a forest in Seattle.
The next, his pet was being torn apart by a "gray" - an alien being with an elongated head, smelling of rotting fruit.
Mr Reed, a former child-developmental psychologist, says he took the alien home and lived with it for nine days in which it communicated via telepathy and was able to pull thoughts from his mind.
Mr Reed and others, including Uruguayan Rafael Ulloa who says aliens in spaceships spirited away people from New York's twin towers in the September 11, 2001, attacks, gather in Lima this week for a world extra-terrestrial congress.
Peru has long been a mecca for mystics and there have been abundant reports of flying saucers, especially over the southern town of Chilca.
Some locals say aliens imbued mud springs there with special curative and fertility powers.
The congress is organised by the Alfa y Omega group that believes a fleet of UFOs will fly to Earth at the end of the world and Christ could use one for his second coming,.
During its October 6-9 run, the congress will pore over photos and grainy films of bright flashes and spooky shapes believers say point to alien life forms.
