9/19/61, Betty & Barney Hill observed a bright light in the sky following them. Upon arriving home they'd lost 2 hours of time. Betty began having nightmares in which she was taken aboard an alien spacecraft and medical experiments were performed on her. In separate hypnosis sessions, she & Barney described similar experiences. Betty was shown a star map which she was able to reproduce later, which some believe is showing Zeta Reticuli as the aliens’ home.
