I have never been abducted by anyone who admitted to being an alien, although some of my babysitters probably just weren't owning up. If you want some insight into what people believe it was like, I suggest you read the two or three books written by Whitley Streiber around 1983-5 on the subject.

While the information is often "anecdotal" the actual numbers of anecdotes and the unusual points of commonality they seem to come up with from apparently independent sources is a faskinatin' puzzle.A
