Alien abductions have occurred throughout history, to take an instance from The Bible we only need to look at the narrative of Ezekiel's strange encounter and subsequent disappearance. These abductions by alien visitors persist to this day and it has been estimated that as many as 100 million people have had abduction encounters. So what is it these people experience?

A Gallup poll a few years ago estimated one third of all Americans believe aliens have visited the planet Earth, and of these a large percentage believed alien abductions were happening frequently.

Abductions can occur at anytime of the day or night, they have happened in big cities and isolated outlying areas.

Strangely many alien abduction reports obtained from abductees follow a similar thread. The pattern in most instances goes like this.

A light is observed outside the bedroom window and shines in filling the room, aliens generally, though not consistently are referred to as Greys, enter the room either through the doorway or walls. In some cases the victim simply awakens to find them standing by the bed.

The abductee is paralyzed, completely unable to move, resist or speak. Anyone else present remains asleep, utterly unaware of what is happening. This lack of response from others present in the area has led to hypotheses that some kind of apparatus is used to shut down the sensory centres of the brain, by temporarily shorting those centres out, while retaining a rest like state.

The abductors repeatedly reassure the victim, either telepathically or by touch that what they are doing, or have to do, is necessary and for some kind of greater good.

The individual is then floated out of the room, sometimes via the door, sometimes through secure windows or even walls, solid matter appears to be no barrier, as the abductee along with the abductors are beamed into a waiting alien craft.

Once on board the victims find themselves in an examination room, their clothing removed and on a hard surfaced table.

Various medical procedures and examinations are performed, often gynaecological in description; implants may be surgically implanted into the nose, ears, behind the eyes or hypodermically. Samples of skin, semen, blood and other tissues are apparently taken. Sometimes the victim is induced to couple with another human being present or with one of the aliens. Throughout these practices the abductee is repeatedly reassured that this is for the greater good.

In some cases telepathic messages are conveyed to the abductee. In many cases these are of impending doom, knowledge of benefit to humanity, or of the aliens dying planet and the need to redeem their race.

The abductee is often told they were chosen to either help continue the alien race or that they are going through this to aid in salvaging humanity.

They are then often escorted to rooms containing humanoid babies or youngsters which are half alien – half human hybrids, they are then informed that some of these children are theirs and are enthusiastically encouraged to personally interact with them.

Others not involved in the breeding programs are often given tours of the craft and information is revealed about future events on earth, wars, famine, natural disasters and they are told that mankind needs to alter its ways.

Clothing is then returned to the abductee and they are returned to where the abduction originally occurred. The abductors and their craft then leave.

Often the victims are left in a confused or emotionally upset state, clothing is often in a shambles, or in some cases not present at all. Periods of missing time - minutes, sometimes hours have completely disappeared from the individuals memory.

The next day nothing of what happened is remembered, however the abductee may experience nose bleeds, unexplainable scars, bruising or muscle strain, strange marks, pain in the genital region and often what amounts to post traumatic stress symptoms.

Memories of what occurred may surface weeks or sometimes months, later as dreams or recollections initiated by associations or events that recall vague glimpses of what happened, often causing bewilderment.

Occasionally if the abductee seeks help, an investigator will refer them for regressive hypnosis. This is one of the main tools investigators use to release suppressed memories of an alien abduction, however it has not been proven to be a very reliable tool as it is very easy for the hypnotherapist to instil or even encourage these memories during a session unintentionally.

Many of these abductions go unreported due to the fear of ridicule and humiliation it would cause, particularly where experiments of a sexual nature were involved. Many remember the incident from the motion picture "Independence Day" where the town Sheriff and his companions make fun of the Crop Duster Pilot, about his abduction and "experiments of the sexual nature" being performed on him, many abductees get this very same type of community reaction if their encounter becomes known to the public.

What is the purpose of these Abductions?

A common theme, through most present day abductions is that they are for an experimental interbreeding programme, the production of a half-alien, half-human hybrid.

Some abductees have been told that this will allow prospective generations of aliens to better fit in with humans, or that their abductors are a sterile race and the integration of human genes into the species will allow them to re-establish their race.

Many people are familiar with the Betty and Barney Hill case, which is cited as the commencement of the abduction phenomena. One test their abductors carried out on Betty was the insertion of a needle into her navel and the extraction of some fluid. This routine was not known to our medical science at the time, but is now called amniocentesis and is utilized to test for foetal abnormalities.

Barney Hill also disclosed that he had a sperm sample extracted as well.

This was a distinct attempt at checking the human reproductive system to consider whether humans would be compatible for their breeding programme.

Following this, female abductees began showing signs of pregnancy which would often disappear after a few weeks as if the abductee had never been pregnant at all, with no signs of a miscarriage, it's as if the foetus just wasn't there anymore.

Often the foetuses were more advanced than they should have been when detected for the indicated time of gestation. Many cases were put down to phantom pregnancies or that the patient had aborted but just not realised it. Later research however began to uncover that these woman had been submitted to some type of foetal implantation procedure, and when the foetus was developed enough, was then extracted for external incubation.

This must not have achieved the desired affect as in recent abductions direct mating has become a consistent feature of more abduction accounts.

A classic example of this is the encounter of Antonio Villas Boas.

Villas Boas' encounter took place on October 15th 1957, when the 23 year old was laboring, at night, on the family farm in Brazil. He was abducted by 3 figures in strange suits and taken aboard a craft, there he was induced to make love to a very beautiful, almost-human looking woman, after this Villas Boas was deposited back in the field from which he had been taken.

This sort of encounter is now becoming a more and more common theme in recent abductions. It is easy to witness the progression from breeding compatibility testing, as in the Hill case, to experimental foetal implantation, through to direct mating, as was the case with Villas Boas. Perhaps even the examinations performed on abductees prior to this were also a step in the hybrid programme to verify compatibility, forms of DNA testing, skin samples etc and physiology are all details that any advanced civilisation would check first.

Are we merely a vast genetic repository for some advanced alien civilisation? Maybe but only the night visitors know.
