About one in every one thousand people has been abducted by a UFO whether they know it or not. The action of being beamed into the ship with a blue ray actually suffocates the person, casing all oxygen to be sucked from the person's cells, so that they hover near death for a moment. Upon arrival in the ship, they are revived by another ray that restores oxygen into the cells.
Many abductions are of a quite cruel nature.
Humans would not want to remember what happened in some of the clinical experimentation or examinations that occurred. Abductions are reported in every country in the world. They take place on deserted roads, in country fields, the abductees home, and even in the largest cities. The clothes are removed. Subjects lay on medical tables.
