witnesses can be so reliable
As a researcher and hypnotherapist I have worked with people who claimed to have been abducted by extraterrestrials. I have interviewed UFO researchers, scientists, authors, and people who claim to have secret information.
Physical evidence seems to support many case histories, though some experiences may actually be caused by dreams, mental problems, media indoctrination, or misinterpretation of what the person has seen. All leave an imprint on the psyche of the person, or persons (multiple abductions involved).
Most countries have reports of alien abductions. They occur in large cities as well as the rural areas.
Abductions occur at any time of the day or night.
Many abductions are not reported, because there is no one to tell, or the abductee fears ridicule from others, especially if they feel they have been sexually violated.
People wo have been abducted many times keep journals to determine patterns or timetables. They sometimes write books about their experiences.
Abductees have tried many interesting techniques to protect themselves, but to date, I know of no one specific approach that prevents these experiences.
Abductees have reported attempts to video or photograph the events. Some abductees have experimented with infrared film. Most footage is useless.
My opinion of this experience: We are all part of an experiment/ experience/ program of some kind. The Grays have always been part of the program. If you can remote view and you get close to their eyes - you will see that the Greys are machines - computers - the watchers - who take people in and out of the porgram to some do sort of reprogramming - like the movie Matrix - The Holodeck in Star Trek. It is all an illusion but this is a nasty part.
Often abductees are told that the experience is for some 'greater good'. Always remember that anyone who does anything to you without your permission - or makes your soul feel uncomfortable - does not have your best interests at heart. Be careful what you believe.
