Context
The Fazenda Vale do Rio do Ouro lies in the municipality of Alexânia, Goiás. Sources place it between 90 and 120 km from Brasília. Its owner was Wilson Plácido de Gusmão. Revista UFO dates the story to 15 June 1967, and to a dream. Wilson saw a small glowing disc circling inside his bedroom. It hovered about a metre above his head and shone a beam of light on his face. Other accounts begin in September 1967, when a small light started approaching the house. It would stop about 200 metres away, stay two or three minutes, then move off.
