A Norwich woman's encounter with an "alien" are among the secrets revealed in official UFO files.
The woman's report is within the third set of UFO documents to be released by the Ministry of Defence, reports the BBC.
The "completely terrified" woman contacted RAF Wattisham in Suffolk to report her close encounter with a man claiming to be an alien in November 1989.
She said she met the fair-haired man with a Scandinavian-type accent as she walked her dog on a sports field.
He told her crop circles were caused by others like him who had travelled to Earth and that the purpose of his visit was friendly.
He then said he had spoken to her because he felt it was important to have contact with humans even though he had been told not to.
As the unidentified woman ran home she heard a loud buzzing noise and turned to see a large, spherical object, glowing orange-white, rise steadily until out of sight.
A letter from RAF Wattisham to the MoD and Norfolk police described it as "one of our more unusual UFO reports".
It is one of the many reports in the files, which can be downloaded from the National Archives website, and are being released as part of a three-year project.
UFO expert Dr David Clarke said: "The vast majority of reports are ordinary things seen in extraordinary situations.
"I don't think there's any solid evidence that we have been visited by intelligent life but I don't think you can rule that out."
