They always overstate abductions. ;)
Actually, the reverse may also be true.
When you consider that the number of abductees consists of those people who either consciously remember being abducted or those who, after having PTSD or other problems, decided to undergo regression hypnosis and then discovered their abduction, there may be many, many more who are abductees but are unaware of it.
Many people, perhaps most people, would be afraid to undergo regression hypnosis for what they might learn. I count myself among that number.
