The term "contact" refers to the interaction with aliens by people of their own free will.  The term "abduction" refers to a person being taken or manipulated by aliens without their consent or knowledge.
 
The studies of Thomas Bullard, who reviewed more than 300 cases of abduction for the study funded by the Fund for UFO Research, indicates that there is a general scenario that occurs when people are abducted.  This general scenario may include one or more phases where the individual is: (1) Taken, (2) Examined, (3) Implanted with devices, (4) Communicated with, (5) Taken on a journey, (6) Subjected to psychic experiences, and (7) Returned to their point of origin.
 
Bullard had the following conclusions: human abductions are widespread in nature.  The people who are abducted represent a wide cross-section of society and are free of psychosis.  They can be from any age bracket, but most are initially taken when they are fairly young.  Some cases feature spontaneous recall of the experience.  But, most abductees do experience memory blockage, especially those who are abducted repeatedly.
 
Abductions by alien entities are a reality shaking experience for many people.  The technologies involved allow the aliens to control virtually every aspect of an individual's perception, experience, and memory.  A significant portion of those that have been abducted remember the experience without hypnotic regression. The extraterrestrial biological entities (EBE) have complete mastery over both human biogenetic systems and the finer biofields that encompass areas all the way to the astral and beyond.
 
It would seem that almost anyone may be abducted and that all phases of human existence are interesting to aliens of one kind or another.  Anyone can be chosen, from the poorest, least educated to the most economically and politically powerful people, regardless of age, race, or religious conviction.  And, as many men are abducted as women are.
 
One thing is apparent: people have been abducted by the Grays for a long time.  We have many cases where the abductee may be the third or fourth generation in his or her family to experience this contact.  We also have one case where a person is aware of having had Gray contact in her previous lifetime and with the same entity she has seen repeatedly in this lifetime!  The Aliens have also been training the abductees on weapons and in aircraft, in order to have those abductees actually fight an enemy of the Grays, possibly the Blonds, sometime in the near future.
 
Most Gray abductees are first taken as children.  Many adult abductees know or feel that their children are also being abducted.  It would seem that most children who appear to be involved don't want to consider the possibility of actual abduction or think about it at all.  It would also seem that the best policy with most children is to leave it at that and not push them to remember.  Children and adults alike, if they are involved, will tell you of their weird dreams and experiences even when they don't believe there is anything going on.
 
         Women are frequently abducted largely for reproduction purposes, though some never experience that kind of interaction.  Some of those who are involved in that part of it report that their earthbound, human children who live with them, were supposedly allowed by the aliens in exchange for the half-breed children that are taken away.  Often, when a woman is told this, she has only one earthbound child.
 
Genetic cross breeding work involves subjecting human females to "short-run" pregnancies of approximately three months, after which the cross-bred fetus is removed and the female is returned, usually unaware of the experience.  Some cases indicate that newly fertilized eggs (fertilized with alien sperm) are inserted at the same time that a crossbred fetus is removed, which results in a constant state of pregnancy for significant periods of time.
 
         Such abductees who are aware of having produced half-breeds or hybrid children that "live with the aliens" have several different reactions to the situation.  Some are perfectly happy with the program as it is.  Many women don't express any opinion about it at all because they don't see it as being anything that they can do anything about.  Some are repulsed by the crossbred children and by their own involvement with them.  Some have felt that the hybred children that they produce will be used against us.
 
Others love their half-breed children as they would any others.  Many who feel this way would like to recover their children and bring them back to Earth where they would have a better life than with the aliens.  Many also feel that the children are better off where they are.  But, they would certainly like to have more open contact with them and more interaction with their children.
 
Some major indicators of alien interaction and possible hidden involvement:
 
         A.   Missing time.
         B.   Waking up during the night or in the morning with unusual
                bodily sensations, such as tingling, numbness, dizziness,
                heaviness, or paralysis.  Any of these are often accompanied
                by disorientation.
         C.   Nightmares or vivid dreams of aliens and/or their technology.
         D.   Sleep disorders and waking up consistently at a specific time.
         E.   Physical marks or evidence of bodily manipulation.
         F.   Repeated sightings of alien craft.
         G.   Clear remembrance of alien contact and interaction.
         H.   Healing or inexplicable improvement in physical conditions.
         I.    Reactions of fear, anxiety or unusual bodily sensations upon
               viewing visual images of aliens or their technology.
         J.   Feelings of having had a communication.
         K. Unexplained behavior totally inconsistent with previous patterns.
 
       Any or all of the above indicators may appear in combination with other ones.  Many of the indicators could also signal a physical problem requiring medical attention.
 
Physical problems from abduction can range from scarring (from having scoops of flesh removed) to intense organic problems.  For human females, the problems often have a greater scope than with males or children.  Since human females are used as part of the hybrid breeding process, reproductive problems from organic over-uses of reproductive processes take their toll, often reflected by vaginal or navel (the navel is a favorite injection site) discharges.  It is also common for female humans to acquire various infections.  These infections are often based on plant-like (such as yeast) or staph type organisms.
 
Psychological problems can take their toll in the form of neurological disorders or disorders relating to the higher (bio-electrical) fields of the body, which have an effect on all fields (including the formative, repair-oriented field matrix of the human body).  Use of implants often has an effect on pituitary or pineal gland function, which can also have marked psychological effects on the abductee.
 
        Psychological symptoms can result from buried or blocked traumatic experience, producing anxiety that sometimes drastically interferes with the life of the individual.
 
Since abductions, especially of human females and children, seem to occur mostly at night, sleep patterns are disturbed.  The individual may have encounters during a specific time period of the night, which causes sleep anxieties and a generalized deterioration of health over a long period of time.
 
        There are also sexual components to abduction experiences.  They can be the result of an actual sexual experience with an alien, the result of examination or probing of sexual organs, or the direct collection of sperm or eggs.  Research on the production of hybrid alien children using human females seems to indicate that alien sperm are most often mated with human female eggs.
 
The aliens will test the abductee to see what kinds of emotional frequencies are produced when different kinds of stimuli are directed at the abductee.  Stimuli can be physical (subsonics, light, or various forms of energy) or mental (inculcation of vivid images into the mind of the abductee).  The aliens can examine what mental images are stored in the mind of the abductee and will select those images that are tied into emotions that they wish to evoke.  The reason behind this is that the aliens involved can "collect" the energy that is radiated on certain frequencies and convert it to a transportable form that they can store for use later on.
 
The Grays also have the ability to pickup and gather the energy emitted through the eyes (sometimes called elliptic energy, or biological energy).  The Gray that is uppermost in their group hierarchy takes a position in front of the abductee in order to absorb this energy, which is upgraded in quantity and quality by induction of emotional processes in the human.  This process is not done as often with children as with adults.
 
Childhood symptoms of abductions that adults can recognize may include missing time, inexplicable wounds, unfounded fears, nightmares, physical scares with no known origin, and other symptoms similar to adults.
 
        Children are sometimes abducted and never returned to their point of origin.  The Grays may abduct a human child and raise them in their own environment to eventually become a manipulated human that they can use for their own purposes.  Reptilian aliens are known to be carnivorous.  It is also known that, as far as the humans are concerned, they prefer human children to adults.  The bodies of human children are relatively uncontaminated with tobacco, alcohol, and other substances that are distasteful to that species.  Research indicates that human children are being collected and stored by some species for that purpose.
 
There are several types of beams that are used by the aliens.  One in particular, the blue colored ray, is used for paralyzing, capturing, and transporting humans.  The action of being beamed into a ship temporarily suffocates the human, as all the oxygen is suddenly removed from all the cells of the body during the process.  Another type of radiation restores the oxygen to the body upon arrival.  When the aliens themselves use beam transport, a different type of beam is used that permits them to arrive completely alert.  The blue beam has been described quite frequently by abductees.
