Another subject linked with UFO's is Alien abduction,here is an introduction article I will follow this up with some of the more famous cases.Source Wikipedia.
The term "abduction phenomenon" refers to claims of kidnapping and removal from familiar terrestrial surroundings by non-human creatures.People claiming to have been abducted are called "abductees" or "experiencers." The abductors, usually interpreted as being extraterrestrial life forms, are said to subject experiencers to a forced medical examination that emphasizes the experiencer's reproductive system.Some aspects of the abduction experience are more benign, however. The abductors often warn against environmental abuse and the dangers of nuclear weapons.Consequently, while many of these purported encounters are described as terrifying, some have been viewed as pleasurable or transformative.
The first alien abduction narrative to be widely publicized was the Betty and Barney Hill abduction in 1961.Reports of the abduction phenomenon have been made around the world, but are most common in English speaking countries, especially the United States.The contents of the abduction narrative often seem to vary with the home culture of the alleged abductee.
Mainstream academics and members of the skeptics movement generally doubt that the phenomenon occurs literally as reported, and have proposed a variety of alternate explanations. Such skeptics often argue that the phenomenon might be a modern-day folk myth or vivid dreams occurring in a state of sleep paralysis. The alien abduction phenomenon has been the subject of conspiracy theories, and as such it has become a staple of popular science fiction works such as The X-Files. At the present time no generally accepted empirical scientific evidence exists to corroborate the claims of abduction proponents.
Few mainstream scientists believe the phenomenon literally occurs as reported. However, there is little doubt that many apparently stable persons who report alien abductions are sincere: as reported in the Harvard University Gazette in 1992, Dr. John Edward Mack investigated over 60 claimed abductees, and "spent countless therapeutic hours with these individuals only to find that what struck him was the 'ordinariness' of the population, including a restaurant owner, several secretaries, a prison guard, college students, a university administrator, and several homemakers ... 'The majority of abductees do not appear to be deluded, confabulating, lying, self-dramatizing, or suffering from a clear mental illness,' he maintained." "While psychopathology is indicated in some isolated alien abduction cases,"assessment by both clinical examination and standardized tests has shown that, as a group, abduction experients are not different from the general population in term of psychopathology prevalence." Other experts who have argued that abductees' mental health is no better or worse than average include psychologists John Wilson and Rima Laibow, and psychotherapist David Gotlib.
Some abduction reports are quite detailed. An entire subculture has developed around the subject, with support groups and a detailed mythos explaining the reasons for abductions: The various aliens (Greys, Reptilians, "Nordics" and so on) are said to have specific roles, origins, and motivations. Abduction claimants do not always attempt to explain the phenomenon, but some take independent research interest in it themselves, and explain the lack of greater awareness of alien abduction as the result of either extraterrestrial or governmental interest in cover-up.
A variety of motivations are attributed to alleged abductors. These include:
Numerous reports that form a loose narrative around long-term surveillance and interaction with humans. The entities state that the abductee has a unique characteristic, resulting in repeated abductions, implating information subconsciously for later "activation". Some times this is related to major changes affecting the Earth and the entities' desire to help.
When abductees ask why they are being studied or undergoing surgery, the entity may answer with a statement like "We have the right to do this."
Although different cases vary in detail (sometimes significantly), some UFO researchers, such as folklorist Thomas E. Bullard argue that there is a broad, fairly consistent sequence and description of events which make up the typical "close encounter of the fourth kind" (a popular but unofficial designation building on Dr. J. Allen Hynek's classifying terminology). Though the features outlined below are often reported, there is some disagreement as to exactly how often they actually occur. Some researchers (especially Budd Hopkins and David Michael Jacobs) have been accused of excluding, minimising or suppressing testimony or data which do not fit a certain paradigm for the phenomenon.
Bullard argues most abduction accounts feature the following events. They generally follow the sequence noted below, though not all abductions feature all the events:
Capture. The abductee is forcibly taken from terrestrial surroundings to an apparent alien space craft.
Examination. Invasive medical or scientific procedures are performed on the abductee.
Conference. The abductors speak to the abductee.
Tour. The abductees are given a tour of their captors' vessel.
Loss of Time. Abductees rapidly forget the majority of their experience.
Return. The abductees are returned to earth. Occasionally in a different location from where they were allegedly taken or with new injuries or disheveled clothing.
Theophany. The abductee has a profound mystical experience, accompanied by a feeling of oneness with God or the universe.
Aftermath. The abductee must cope with the psychological, physical, and social effects of the experience
There have been a variety of explanations offered for abduction phenomena, ranging from sharply skeptical appraisals to uncritical acceptance of all abductee claims.
Some have elected not to try explaining things, instead noting similarities to other phenomena, or simply documenting the development of the alien abduction phenomenon.
Others are intrigued by the entire phenomenon, but hesitate in making any definitive conclusions.
If actual "flesh and blood" aliens are abducting humans, there should be some hard evidence that this is occurring.Proponents of the physical reality of the abduction experience have suggested ways that could conceivably confirm abduction reports.
One procedure reported occurring during the alleged exam phase of the experience is the insertion of a long needle-like contraption into a woman's navel.Some have speculated that this could be a form of laparoscopy.If this is true, after the abduction there should be free gas in the lady's abdomen, which could be seen on an x-ray.The presence of free gas would be extremely abnormal, and would help substantiate the claim of some sort of procedure being done to her.
